My Husband's Mistress Forced Me to Step Down

" It was a Sunday evening when I got a call from Lucas while having dinner. "Ava, I'm sorry. I cheated again." I calmly put some vegetables into the pot and replied, "Buy me a car to apologize, and we'll move on." Lucas fell silent for a moment before dropping the bomb. "She's pregnant." I stopped eating and stared at the bubbling broth. "Oh, that won't do. You'll have to add an apartment too." ... 1 After my face was registered for the lock of the 4,600 square foot penthouse downtown, the keys to a white Cullinan also arrived in my hands. Lucas, my fiancé, truly lived up to his reputation as the cream of the crop among the city's second-generation rich. This time, his mistress was a stunning woman named Mia, who confronted me aggressively. "Break up with Lucas! He loves me!" "While you were sitting at home alone, we were kissing by the lake! He took me horseback riding and we made love passionately every night at the resort! That's when the baby was conceived..." What a riveting love story. If I'd come across it on TikTok, I'd have given it a like. My gaze lowered to Mia's slightly protruding belly beneath her heaving chest. I'd seen many mistresses before.

Anyone still throwing themselves at him would be treated as "asking for it." "As for the authenticity of the child, I'll take you for a paternity test tomorrow. Once we have the results, we can discuss compensation." Mia slammed the table and stood up. "Ava, are you even human? You're talking about me and my baby like we're commodities." I remained as calm as still water. "Being a mistress comes with its own treatment. Miss Mia, if you could reach Lucas and make him take responsibility, would you be sitting here for three hours waiting for me?" Mia's expression faltered, and I delivered my final blow gently. "Coincidentally, Lucas always uses protection when he sleeps with others. I never give him condoms that are more than six months old, and I insist that he confirms the other person's health status before sleeping with them. How strange that this time there was an accident?" Hearing this, Mia was not only shocked by the content of my words but also showed a moment of panic. Her fingers, gripping the cup, trembled and turned white. "Maybe... it was just bad luck..." Her voice trailed off, quickly swallowed by her cup. I smiled without speaking. Her phone rang. Suddenly, Mia's gloomy face brightened. "I'm not afraid. You can check all you want. But I'm telling you, if t...
