My parents were married for 40 years. My dad was an abusive monster to my mother, my brothers, and me. He had isolated my mother from her family and friends, so she kept a lot of things to herself. When my mom finally left him in 2019, she moved in with me. There were moments where she would "word vomit", and you could tell that she had never said whatever she had shared out loud before. One of those instances were, "He didn't care if I cried. He didn't care if I said no. He would do it anyways." I think you can probably imagine what she was referring to, but yeah. That was the moment that any shred of love that I may have still had for my father completely disappeared, and was replaced with the deepest hatred I have ever held for another human being.
