My Daughter Started Coming Home from School in Tears and Stopped Talking to My Wife

When my daughter Demi, 13, started coming home from school crying, I thought it was typical teenage struggles. But her silence toward her mother, Nora, hinted at something deeper. Our once-happy life—stable job, loving marriage, and a joyful daughter—began unraveling.
Demi’s red eyes and distant demeanor persisted. She brushed off my concerns, snapping when pressed. Nora, busy with work, hadn’t noticed but promised to talk to her. That evening, Demi exploded at Nora, refusing to speak. Worried, I visited Demi’s school and saw her with a girl, Sierra, who looked eerily similar. Shockingly, the driver picking Sierra up was Todd, Nora’s old friend, who ignored me and sped off.
At home, Demi revealed Sierra was her sister. She’d met Todd, who claimed to be her biological father, showing a photo of him with a pregnant Nora. Confronted, Nora admitted she cheated with Todd years ago, and Demi was his daughter. Devastated by her 13-year lie, I couldn’t forgive her. Demi and I moved out, and I filed for divorce, gaining full custody. Though heartbroken, we began rebuilding our lives together, step by step, leaving the betrayal behind.
