Best Friend Cheating Short Stories & Novels

On the fifth anniversary of my marriage to Vicente Buckley, he violated my trust by sleeping with my best friend Kinsley Gilmore, on our bed. Through the camera, my son Jamie Buckley's childish voice sounded. "Kinsley, I'll keep watch at the door. I won't let my mom come in!" As if rewarding him, Kinsley pecked Vicente and suggested, "Your son is great. Don't you think about having another child with Patricia?" Vicente responded by covering her face with a pillow, saying, "The scar on her belly disgusts me."

In our third year of trying for a baby, Gideon Tarrant insisted that I go to the snowy peaks of the Kestrel Range to pray for a child. "The old folks say that if a wife climbs Hallow Peak and kneels to pray every three steps, heaven will send her a baby." Because of that, I faced the blizzard in the bitter subzero cold and knelt my way up from the foot of the mountain. When I was nearly at the summit, the smartwatch on my wrist suddenly buzzed. The health app showed that Gideon's heart rate was spiking. Right after that, a video synced automatically to our family cloud album. In a delivery room, Gideon was cutting the umbilical cord with red-rimmed eyes. The woman in the bed was my best friend, Amanda Crowley. Six months earlier, she had come to me in tears and told me she was pregnant and unmarried. My heart went out to her, so I sent her 80,000 dollars. She did not accept it. She only sent back one line: [Hazel, thank you for giving me the best of everything.] I thought she meant all the ways I had looked after her over the years. At this moment, as I watched the video, I saw that the people gathered around her bed were my own family. My father was holding the baby, tears of joy running down his weathered face. My mother sat at the bedside, her eyes full of tenderness. "Just focus on getting your strength back. We'll make sure Hazel doesn't find out." My brother went even further and pressed a thick envelope of cash into Gideon's hand. "Gideon, once Hazel's prayed that blessing down for Mandy, we'll have her clear out and make room for our big boy!" My husband, Gideon, held Amanda's hand tightly and pressed a tender kiss to her forehead. "This time, I'm never going to let you or the baby get hurt again." I lifted my head stiffly and looked up at the prayer ribbon tied to the branch above me. Gideon had written the wish on it himself. It read: [May my beloved be kept safe.] It turned out I was never a part of the beloved he had been praying for.

I had been dating my boyfriend, Julian Hayes, for four years, yet my best friend Fiona Blake still looked more like his girlfriend than I did. Whenever the three of us went furniture shopping, the sales associate would hand Julian and Fiona a catalog for couples. Whenever we went out for fondue, the server would ask if Julian and Fiona wanted a photo together. At the beach, a stranger once handed me her phone and asked, "Would you mind taking a picture of your friend and his girlfriend?" I smiled, took her phone, and raised it to take the picture. On the screen, Julian and Fiona looked every bit like a couple. Fiona always brushed it off. "We just have similar face shapes. It's a coincidence." Julian always reassured me. "It doesn't matter what anyone else thinks. You're my only girlfriend." And year after year, I believed him. By our fourth year together, I started pushing him to finally set a wedding date. He said he was too busy and promised we'd set the date the following month. But when the next month came, he had another excuse. Fiona's visa was about to expire. She wanted to stay in the United States, and the easiest way to get a green card was through marriage. I stared at him. "And so?" He was silent for a long moment before finally answering. "I'll marry her first and sponsor her application. It's only a formality. Once she gets her green card, we'll get divorced." For a moment, I couldn't believe what I was hearing. "And what about me?" He answered without hesitation. "Just give me a few years. It'll be over before you know it." A week later, Fiona posted a photo on Instagram. She held up their marriage certificate and leaned against Julian's shoulder, smiling so widely that her eyes crinkled. The caption read, "As of today, it isn't a coincidence. It's fate." I went back through years of messages. That was when I finally realized the truth. Julian had never once told anyone I was his girlfriend. Whenever strangers mistook Fiona for his girlfrien

During our beach vacation, my wife, Carla Locke, lets her guy best friend, Alex Dugan, rub sunscreen all over her. "What have you been eating lately? Feels like you've gone up a cup size." The moment I see Alex's hand lingering on Carla's chest, the drink slips from my hand and shatters on the ground. Carla gets upset and tells me off for being so insecure. "We're just messing around. Why do you always overthink everything?" Alex shoots me a challenging look. "Don't be upset, Hubert. Carla and I are just friends. Sometimes, I wish I'd been born a woman. Then, people wouldn't keep misunderstanding our relationship." Carla leans into his embrace and shakes her head as she looks at me. "I wish you'd stop being so sensitive about this. Stop trying to ruin our friendship." However, Carla and Alex don't know that I'm from another world. After completing my mission in the previous world, the system rewards me with one wish. Since they insist they're just best friends, I'll be more than happy to grant his wish to become a woman.

Before my engagement, a fire broke out in my dressing room. The explosion sent shards of glass deep into my body. My best friend, Monica Addams, shielded me as we escaped the flames.  At the hospital, she stayed by my side as I clung to life.  She called my fiancé, James Miller. However, his response was dismissive. “Veronica isn’t feeling well, and I’m accompanying her to get an IV drip. If it’s no big deal, just drop it.” Furious, Monica unleashed a string of curses and called her own boyfriend, Lucas Smith, asking him to help find a specialist.  He brushed her off, too. “Stop overreacting. Veronica’s sick, so I’m getting her some medicine.” When I narrowly escaped death and met Monica’s gaze, I said in a low voice, “I want to call off the engagement.” Without hesitation, she responded, “If you end yours, I’ll end mine.” That was when both men panicked. 

At the company team dinner, my boyfriend, Jax Vance, went out of his way to grab two drinks. He handed one to Chloe Ward, my best friend sitting across from us. He set the other one down in front of me. My friend smiled and bowed her head. "You're so thoughtful, Jax. You always remember my stomach can't handle ice." I looked down at the mango slush. I pushed the cup away without a word. "What's wrong?" Jax asked casually. "I'm deathly allergic to mangoes," I said. "Did you forget again?" He paused for a second. Then he let out a careless laugh. "It's not a big deal," he said. "Just scoop the fruit out." He remembered every detail about her. She didn't eat cilantro. She hated onions. She only drank her tea with thirty percent sugar and no ice. But he forgot that my throat would close up if I touched a mango. To him, that was just something I could "scoop out." I finally saw the truth. When someone didn't care, even life-or-death moments would mean nothing to them. On the ride home, I sat alone in the backseat. I watched the two of them in the front. They looked so good together. Suddenly, a strange wave of relief washed over me. A relationship where my life didn't even matter? I didn't want it anymore.

While strolling around the mall, I bend down to tie my shoelaces. When I lift my head again, my boyfriend, Lucas Carter, and my best friend, Kimberly Wendell, are already over 30 feet away. Just as I am about to catch up with them, I notice that the spot that should've been mine is slowly vanishing as the two walk closer and closer. Eventually, they are shoulder to shoulder as they talk about topics that I can't join in on. It's as though a third person was never there. During our university years, Lucas and Kimberly were known as the the school’s most promising “twin stars”. This continued even after we graduated, with them becoming the youngest chief physicians at the hospital. Meanwhile, no matter how hard I work, I can only trail behind them as an ordinary nurse. Lucas is always patting my head, saying, "You're cute, even when you're a little slow sometimes." Then he turns around and works seamlessly with Kimberly to perform one complex surgery after another. As I stare at their backs, I suddenly feel utterly exhausted. I no longer want to continue down this road, forever chasing after Lucas.

My boyfriend, Tyler Olsen, only wants me when I stop wanting him. The more I love him, the less he can stand me. At the elaborate proposal I plan for him, Tyler walks in with his arm around my best friend Winona Carter's waist. Then, in front of everyone, he makes an announcement. "Winnie and I had sex." He watches the happiness and anticipation slowly drain from my face before asking me the same question for the 27th time. "You don't love me as much anymore, do you?" I nod, and Tyler immediately lights up. "That's great. Now, we can be perfectly fine together again for a while." Over our eight years together, he's hugged Winona, kissed her, held her hand, taken her on dates, and celebrated anniversaries with her. He's used every method he can think of to wear away my feelings for him. Only when I stop loving him can he love me. Winona gives his chest a playful pinch, then turns to me with a pout. "I even lost my virginity to him so you two could stay together. You'd better make it up to me." Tyler smiles at her. "Alright, alright. You're the hero here. Whatever you want, I'll get it for you." The two of them discuss what he should give her as compensation while I watch in silence. Without a word, I toss the roses in my hands into the trash. Tyler has no idea that I've already promised my mother to move abroad with her for good if the proposal falls through.

Someone texted me halfway through the wedding. The message read, "I had sex with your husband. Doesn't matter if you don't believe it." The message hit me like a hammer, and I stood petrified. Then, the texter sent another message, "Second pocket on the inside of his coat. There's a used condom there from last night. Strawberry. We were setting up the room, and one thing led to another. "We did it everywhere. Balcony, kitchen, and even in your car. He's not allergic to women. He'd gladly sleep with someone before marriage. He lied to you." Everything began to spin. I walked ahead, but my movements felt stiff. I felt as if someone was yanking me forward. I approached the aloof, abstinent man I called my husband. The same man who had to think twice before holding my hand. Sure enough, I found a pink condom in his pocket. Gasps and shouts rippled across the hall, while flashes of camera blazed and blinded the scene. I spun on my heel. That was when I saw my best friend Zoe holding up her phone beneath the stage, a gentle smile hanging on her lips. Something bitter and sad filled my heart. It took me standing here, utterly humiliated, to realize that the very thing I spent my whole life fighting for was nothing but a joke.

Maisie Stone has known Ethan Ford for 15 years. She's gone from being a young woman to a married one. She's also gone from being Ethan's true love to an old flame. He cheats on her repeatedly, and she forgives him every time. After a suicide attempt, Maisie finally sees the light. This rotten world is just a competition to see who can be more shameless than others. In an open relationship, both parties live their own lives. Since he's messing around with her sister, she can mess around with his friends and brothers.

Before the wedding, the coordinator, Rachel Bennett, called me. "Ms. Lane, we tailored the suit to the groom's measurements. Are you sure you want us to change the size?" "Yes," I said. "The groom's changed." My wedding to Caleb was two days away. I'd chosen the venue, designed the invitations, and picked out both my dress and his suit on my own. Every time I tried to involve Caleb in the planning, he only got annoyed. "You know I'm not into all the ceremony. "Don't bother me with this little stuff." Then yesterday, I found an old proposal video on his computer. It was five hours long. Four of those hours showed Caleb painstakingly setting everything up himself. For the final hour, he excitedly walked a woman through every detail he'd prepared before dropping to one knee. "Nina Sawyer, will you marry me?" Nina. Nina Sawyer. Caleb had always told me she was a childhood friend he'd grown up with. Now she was also my best friend, and she was supposed to be my maid of honor. I gave Rachel the new measurements and watched as she carried the suit away. For some reason, tears suddenly started spilling down my face before I could stop them. She startled and quickly handed me a tissue. "Ms. Lane, are you okay?" I wiped my eyes. "I'm fine. Please have the suit altered as soon as possible. I don't want anything delaying the wedding."

I start a livestream in the middle of the road before torching down my luxurious mansion that's worth ten million dollars in front of the entire Internet. Everyone claims that I've gone nuts. "I can't believe she actually burned a mansion that's worth ten million dollars! She must have gone cuckoo in the head!" I watch the inferno from my spot on the street, feeling extremely pleased. When the firefighters and the police arrive at the scene, I honestly admit to having burned down the mansion. Then, I request the police to arrest me on the spot. "I'm an arsonist, you see. I have mental health issues, so please arrest me as soon as possible. Otherwise, I'll burn down more houses." In my previous life, I had bought this mansion as an engagement gift for me and my fiance, Nigel Taylor. But this was also the very same mansion that ruined my life permanently. Nigel and my best friend, Olivia Williams, had gotten together behind my back. Those bastards betrayed me. After they spent the first half of the night drinking, they sped down the road in a car. But after hitting a few pedestrians, they fled from the scene. Then, they hid the offending vehicle in the garage of the mansion before spending the rest of the night together in bed. The next day, Nigel and Olivia cleared the scene of all traces and made me the perfect scapegoat for their crimes. I couldn't even defend myself when I was faced with all solid evidence that pinned the crimes on me. In the end, I was thrown behind bars. My reputation was instantly ruined. Not only did my company go into bankruptcy, but my parents also fell ill. In the end, they were beaten to death by the debtors who showed up on their doorstep. When I open my eyes again, I've returned to the night Nigel and Olivia are about to commit the crimes. This time, I won't give them a chance to falsify any clues.

On June nineteenth—the day my boyfriend and I had planned to get our marriage license—he vanished without a word. It wasn't until that night that I stumbled across a post on his social media. He'd forgotten to block me from seeing it. "From twenty to twenty-eight, our youth: signed, sealed, delivered." The photo attached showed two marriage certificates. In the wedding picture beside it, a girl I didn't recognize leaned into his shoulder, beaming. Furious, I opened the comments to demand an explanation, and found my best friend's message waiting there instead. [Congratulations to the old flames who finally found their way back to each other!] My chest went tight. My hands shook as I called her. After a long silence, she finally told me the truth. "Yeah. They've been together for eight years. Everyone already knew. We didn't hide it to hurt you. We were just scared you'd make a scene. "Alice and Chase were always the better match. It wasn't easy for them to get to where they are today. Why make things hard on another woman? Just be the bigger person." The tears that fell were cold as ice, but where they landed, they burned straight through me. Twelve years together, and for eight of them, Chase Peterson had loved someone else. Everyone had known. They'd just all agreed to keep it from me.

My best friend, Susie Young, broke a bone while saving my boyfriend's mother. So my boyfriend, Josh Wagner, had to take care of her after work every day. At first, he still came home afterward. Later, he got tired of going back and forth, so he simply started staying at the hospital dorm. Whenever I asked about Susie's injuries, he always looked helpless. "It takes at least three months for an injury like that to heal. She's probably got a long way to go. If it weren't for repaying her for saving my mom, I wouldn't even bother taking care of her." When Susie heard that, she rolled her eyes. "You think I want you here? You can't even peel an apple properly." They acted so openly that it seemed like there was nothing going on between them. Then one day, my blood sugar dropped, and I accidentally fell down the stairs. My arm was dislocated in the fall. Drenched in cold sweat from the pain, I called Josh. He sounded helpless. "Susie has rehab today. I really can't get away. Take a cab to the ER yourself." I dragged myself to the hospital, my arm limp and weak. I stopped by Susie's room. When I pushed the door open, the room was empty. A nurse told me Susie had been discharged two weeks ago and was recovering at home. I stood frozen in the hallway, my hands and feet cold and numb. Then a post from Josh's mom popped up on my phone. "Josh is all grown up now. He finally brought his future wife home!" In the video, Susie and Josh were fooling around in matching aprons. They both saw the post and liked it at the same time. Neither of them offered an explanation.

The day Preston Guest and I were supposed to register our marriage, I arrived at the courthouse only to find him and my best friend, Mallory Vaughn, holding their newly issued marriage certificate. Mallory laughed as she draped an arm around his shoulders. "I lost a bet, so he had to marry me first. We'll get divorced in a month. It won't get in the way of you two being together." Preston slipped an arm around her waist and made me out to be the one who could not take a joke. But he had forgotten what he had said when my mother was rushed into the ICU, and I had begged him to lend me the money for her surgery. "As a businessman, I've always look at value and return on investment. What do I get out of lending you that kind of money? Besides, my money isn't for charity. Adults have to learn how to stand on their own." Yet he had no trouble wiring Mallory three million dollars in startup capital. "Go ahead and use it to get some experience. If you lose it, I'll take the hit." From hiking trips and vacations to marriage proposals and getting married, Preston made bet after bet for Mallory, and every single time, he left me behind. When I did not make a scene, Preston nodded in satisfaction. "That's more like it. Come on, let's grab dinner and celebrate." I pushed them away and handed Preston the breakup agreement I had already signed. "No, thanks. You taught me what independence means: no more spending your money, waiting for you to marry me, or needing you. "I wish you two a long and happy marriage."

After finishing my meal, I went to the cashier counter to settle the bill as usual. It took me longer than usual because the signal was poor. By the time I settled the bill, I could not find Corbin, my boyfriend, or Mabel, my best friend, anywhere inside or outside the restaurant. I called over a dozen times before they finally answered. “You were taking too long, so we just went ahead. “We’re at the Perler bead craft store on the second floor. Hurry up and get over here. The mall was packed and even more crowded than usual for the holiday. The elevator came twice, and both times it was full. So, I gave up and took the escalator instead. By the time I got to the store, every seat at the craft table was already taken. Corbin and Mabel were sitting together, talking about starting at Northbridge University this September and planning out the next ten years of their lives, from graduate school all the way to their doctorates. It was this grand plan for their future, and I had no place in it. They had already made plans to enroll in prestigious universities as early as May. I, however, failed my PSATs and was still considering repeating a year to catch up. Seeing me standing frozen at the door, Corbin said in a helpless tone, “You’re always so slow. Just wait outside for now.” I watched their backs, and a sudden exhaustion washed over me. “Corbin, I’m done chasing you.”

Every year on my birthday, Yale Jensen would find some excuse to disappear into his study and write a letter in secret. The first time I caught him, he refused to let me read it. He only smiled and said, "After we're married." So I assumed the letters were for me, some grand romantic gesture he was saving for our future together. And every birthday, as another letter joined the rest, I kept waiting for the day he'd finally hand them over. That day came sooner than I expected. The night before we were supposed to get married at City Hall, Yale came home drunk from a business dinner. Barely coherent, he murmured, "The letters... have you read them yet...?" I took that as permission. It wasn't until I opened the first envelope that I realized I'd been waiting all those years for letters that had never been meant for me. [Yana, does it really not bother you at all that Tessa and I are together?] The second was worse. [Yana, I made Tessa a birthday dinner today. Thinking about you being overseas and missing out on all of this made me feel awful.] Then the third. [Yana, what am I supposed to do when I keep thinking about you every time I kiss Tessa?] ... I was Tessa Sinclair. Yana Cater was my best friend. The most recent letter had been written two months ago. Unlike the others, it contained only a single line, heavy with regret. [I'm sorry. I'm going to marry Tessa.] The paper crumpled in my fist. Then Yale's phone rang, and I picked it up. "Yale Jensen! You said you used a condom! How the hell am I pregnant?" Yana's hysterical voice came through the phone. I looked down at the letter still clenched in my hand. "He's asleep," I said. "You can call back tomorrow. Unless there's something you'd like me to pass along?"

My mom's dying wish was to see me marry Callum Sinclair. Callum, who lived and breathed surgery, finally agreed to put down the scalpel and come with me to get our marriage license. But just as our number was called over the speaker, my best friend, Helena, stopped him. "The cryo-transplant in Cardiology has gone wrong. The heart muscle is rejecting irreversibly after rewarming." Callum walked away from the window at once. I grabbed his arm. "It's our turn. Sign first, then go. It's three minutes." Callum yanked his hand free. "A life is on the line. I'm a doctor. Three minutes is enough to kill someone." "But my mom is dying too. She wants to see me get married." My tears soaked the front of my dress, and Helena rushed over to pry my fingers loose. "Rosalie, stop this! Your mom is terminal. Nothing can save her now, but other people still have a chance. "You can't let Callum be branded negligent just because of your pathetic selfishness!" But the hospital had just called. My mom's oxygen levels had crashed, and she wouldn't make it through the night. The two of them walked out of the hall, one after the other. I would never fit into their world. They'd both gone to medical school. They never ran out of surgical cases and ideals to talk about. They ate off the same plate and debated the same patient's treatment plan. And me? I could only cook their late-night meals at home and wash their white coats that reeked of disinfectant. They were on the same wavelength. I was always the outsider. A world of life, death, and ideals I could never squeeze into—suddenly, I didn't want to try anymore.

Once the graduation ceremony is over, I take a five-hour train ride to meet my boyfriend, Blake Jones. While I wait for him at the station, I come across a popular post on Reddit. "Am I Overreacting? My Childhood Friend Ditches Me for His Girlfriend, and I'm Pissed. "His girlfriend is my best friend, and the three of us have always been close since we were kids. He's always been really sweet to both of us. "Two days ago, I had a fever, and he rushed me to the hospital in the middle of the night. He even took a day off to keep me company. When my supervisor rejected my thesis, he stayed up all night to help me revise it… "I never used to mind his relationship. But now, whenever I hear him talking to my best friend on the phone, I can't help feeling awful." That catches me off guard. I remember one night when I called Blake, but his phone was switched off. He didn't get back to me until the next afternoon. He said something had come up, but he never mentioned who he'd been with. The comments on the post are all urging the poster to call her childhood friend back and see who he'll choose between her and his girlfriend. I'm just about to type a reply when a notification from Blake comes through. "Babe, something came up. I can't pick you up today. Can you take a cab and come over?" My breath catches. I click on the poster's profile and realize that her location tag is the same city I'm in.

After I moved into a new place with my boyfriend, Simon Zane, getting anywhere felt like a detour. My commute took an hour and twenty minutes, and I was late to work every other day. Our favorite restaurant was two hours away; by the time we arrived, we couldn’t even get in line, so we went home hungry. Visiting my parents meant taking several back roads, and I was too scared to make the trip alone. Whenever I complained, Simon reassured me. "A new place takes some getting used to. Give it time." Then my best friend Wendy Brooks's rental developed a leak, and Simon brought her home without asking me. After a day there, Wendy couldn’t help marveling at the location. "My office is a five-minute walk from here, and several of my favorite places to eat are nearby. Even my hometown’s really close. Everything I need is within a mile and a quarter!" The more she said, the less it sounded like a coincidence. Back in our bedroom, I happened upon the requirements for choosing our new home. The page was crowded with notes: [Wendy Brooks’s office], [Wendy Brooks’s favorite shops]... The home I’d been trying to get used to had never been meant for me. I said nothing and started packing immediately.
