How To Create A Believable Betrayer In Fanfiction?

Dahlia Bernard gave Desmond Sterlings everything, love, loyalty, and a crown he never earned. She picked him from the slums, built him into a CEO, and handed him the keys to her empire. Love blinded her. Desmond repaid her by betraying her, stealing her company, sleeping with multiple women, and getting her own sister pregnant. A community dick, that's all he ever was. Now, Dahlia isn’t just broken. She’s angry. With Ronan Knight, Drawlwood's ruthless billionaire by her side, Dahlia is ready to reclaim everything that was once hers. And this time… mercy is off the table. ********** I was flung aside, my grip on Roselle slipping as I crashed into someone's arms, Ronan Knight. "Hold in your rage, Dahlia," Ronan's voice was calm. "There are better ways to make them pay. Don’t destroy yourself trying to hurt them. That's not how revenge works." I glanced down at my reddened knuckles. Tears blurring my vision. "Then tell me, Ronan… how do I hurt them?" I choked on my tears. "By becoming untouchable," he said softly. "Become more powerful, more successful. A version of Dahlia they could never break. And then… you make them kneel." He leaned in, a wicked promise in his eyes. "I'll help you rise again, Dahlia. And when you do… they'll beg at your feet."

I went through 100 hormone shots for him—just to finally get pregnant. Five years begging those shots to work—all for Rafe Morello. The Don with ice in his veins... but also the guy who used to wipe sweat off my forehead in the middle of the night. Everyone thought we were goals. Then I handed over my lab results, and the nurse paused, blinking up at me. "Sorry, what's your relationship to Rafe Morello? There's already a pregnancy under his wife's name." I froze. Carmela Vitale. His dead brother's wife. Spouse listed: Rafe Morello. Breathing? Suddenly optional. No tears. No drama. I just slid off my ring and tucked it into my bag. Then I called the number buried at the bottom of my drawer. My voice? Freakishly calm. "Yeah. Three days. Pick me up." It wasn't about revenge. I left because I finally got it—some people, you gotta cut loose if you ever wanna stop bleeding. Three days later, he walked into a silent bedroom. On the nightstand: my wedding ring, the signed divorce papers, and a copy of the ultrasound. He sat on the floor and just... kept rubbing that ring. Regret doesn't knock. It floods. And that night, it drowned every lie he thought he could get away with. That was when he finally figured it out—love could wreck a person worse than hate ever could.

In the is novel you will see how the ultimate betrayal of the ones closest to you can either shape your existence or break your spirit and self resolve.

My husband, Damien, loved me deeply—so deeply it felt like I was his whole world. Everyone said he was the perfect husband. Yet, he betrayed me. Not once, not twice, but three times. The first time was three years ago. His closest friend, Aaron, died saving him. Damien kept it from me and secretly married Aaron’s girlfriend, Vivian—on paper. I was heartbroken and ready to leave him. That night, he sent her abroad and fell to his knees, begging me. “Estelle, Aaron gave his life for me. I must take care of his widow. That marriage certificate is just a promise of security for Vivian. Once I’ve avenged Aaron, I’ll divorce her. The only woman I love is you.” I forgave him. The second time came the following year. At a press conference, Damien publicly introduced Vivian as the Mafia leader’s wife. He pulled me aside to explain. “Vivian is the only daughter of the Young family—the Mafia. Our two families joined forces for one reason only: to get revenge for Aaron. I’ve already made arrangements with her. Once we’ve dealt with our enemies, I’ll divorce her and marry you right away.” Once again, I believed him. Then came the third time. Someone drugged Damien at a banquet, and he spent the night with Vivian. He hid it from me until just two weeks ago, when I caught him at the hospital, sitting beside her during a prenatal checkup. That was when I finally learned the truth. He lowered his head, unable to meet my eyes, and spoke in a low voice. “Estelle, it was an accident. Once she gives birth, I’ll send her away. My parents will raise the child, and I swear—neither of them will ever appear in your life again.” In the name of love, Damien pushed me to compromise again and again. Yet now I know. There’s no future left for us. It’s time for me to walk away.

When I was trapped by large columns of fire alongside Reya, my firefighter husband appeared and chose to only rescue her. I got on my knees inside the sea of fire and begged him to save me, too. He jabbed a merciless kick at me. “You are evil through and through, Amaranth. Are you not going to give Reya a chance to live at least? I will never forgive you for starting this fire to kill her!” At this point, his forgiveness no longer mattered. After he rescued his former lover from the scene, I was burned to a crisp alongside the baby inside me.

He was busy kissing her. Catching her breath, she took out the dagger and while he’s busy stripping her skirt. Kill. She stabbed his back. He froze as she met his eyes. He growled in pain as she pushed him hard but he grabbed her neck and throw her away. She hold the dagger tightly as she landed on her foot and knee. “You little bitch.” He growled as she raised her dagger, the tip was facing down and the sharp blade was facing him. He could feel the burn on his back as he laughed. “As I expected, you weren’t just a timid girl, Bella.” He watched those blank eyes. Like there’s no soul on it. Kill. There he heard it again as she attacked immediately and he caught her wrist the blade was near on his eyes. He gripped on it and he pinned her down on the floor as he broke her wrist in anger. She growled in pain as she released the dagger. He took it and throw it out. Now with other hand, he reached her right ear and pulled out an earpiece. He crumbled it into pieces as he growled. “Bella!” He growled. “You little traitor.” She whimpered as she tried to kneed him but his knees were on hers, completely holding her down. “Shhh!” He pressed his forehead to hers as he stared right into her eyes. “Bella, Bella. My. Mate.” She froze and stops struggling. He finally let her go as he carried her to bed. He reached her broken wrist and fixed it. Then, he put cloth around it to support it. He pulled out his phone and rang Paxton. Then, he tossed it away. “Mate,” straddled over her and reached her neck.
