AITA for cutting my father off after he cheated on my mother?

Growing up, I always thought family was supposed to be a sanctuary, a place where love and trust were guaranteed. But the events that unfolded in my teenage years completely shattered that illusion. My father, the man I looked up to, the man I believed would protect and guide me, betrayed not just my mother, but our entire family with a secret affair that slowly poisoned our home. At thirteen, I was forced to witness the unraveling of the world I had known, piecing together hidden lies and quiet betrayals in ways no child should ever have to. From the moment the truth came to light, every interaction with him became a minefield of manipulation, guilt, and emotional ab*se. This is the story of how I came to a point where cutting him out of my life became not only a choice, but a necessity for my own survival, and why standing up to him was the hardest and most painful decision I’ve ever made.

Now it’s Reddit’s turn to weigh in on this mess.

Looking back now, I can see how much this journey has shaped me, how it forced me to confront betrayal, injustice, and the limits of familial loyalty. Cutting my father out of my life was not an easy decision; it tore at the threads of memory, love, and obligation I had clung to for years. But it was also a decision that allowed me to reclaim my sense of self, protect my mother from further harm, and finally begin to untangle the emotional chains he had wrapped around all of us. People may judge me for abandoning him, for refusing to forgive, or for stepping away from the blood tie we shared, but no apology or explanation could ever erase the pain he caused. This story is not just about infidelity; it’s about survival, self-preservation, and the quiet courage it takes to protect your heart when those who are supposed to love you the most choose to betray you.
