When I was in high school I dated this guy who was really possessive, he didn't really let me have friends outside of him , he'd constantly talk to me about how bad he wanted to kill himself and all the things he wanted to change about me. I ended up spending most of my time at his house taking care of him. Eventually I was cleaning some of his things and found an old diary of his from when he was a kid. In it, he talked about how he believed he was hitler in a past life. When I confronted him, he doubled down, said if I told anyone or tried to leave he'd kill himself and write in his note that it was my fault. Eventually he started doing hallucinogens. I had to perform sexual acts on a dealer to get him drugs. When he was high, he'd hit me. When I finally was able to leave, he posted a video telling everyone about his beliefs. When I defended myself from people online, his family threatened to sue me for defamation. I hate that I have to live with what he did to me, and he doesn't.
