My Sweet Mother Destroyed My Cheating Husband

My mother was the only sweet and naive woman in the Palace. She was not hungry for power, did not scheme against others, and did not command any authority. She lived her life in a messy way as the Queen Consort. It was because my father pampered her so much that she became even more ignorant of the world. Everyone in the Palace showed respect on the surface, yet behind her back, they called her an incompetent fool. When I got married, she clutched my wedding gown while she wept and told me again and again, "My little girl, if anyone ever bullies you, do not hold it in. Come home and tell me." I thought she was being naive because no one would bully me when I was the Princess, yet her advice turned out to be right. Before my husband married me, he already had a mistress who had been his childhood lover, and they already had a 3‑year‑old son. After our wedding, he ignored me, humiliated me, and instructed that my allowance be docked. During the Harvest Gala, he held his mistress' hand as they entered the Palace and let her take my seat. He even asked my father to bestow a title upon her. Everyone in the hall stifled their laughter, and it felt like a knife to my heart. I froze and did not dare shed a tear. Footsteps were suddenly heard, and my mother, who had been treated like an accessory by others all her life, started to walk toward us. The look in her eyes was sharp, and her voice was icy. "A title? Why would an insolent mistress think she is good enough to have one? Drag the mistress and her bastard out to be hanged in public."
