So I'm female and in my mids 20s. My BF was in his late 20s and I was 19 when we met, we've been together since then. We met through a social group. I have an abusive family so we moved in together within a few months so I could get away from them. As time when I started noticing disturbing behaviour very slowly develop from him. He was chronically late tp everything, friends parties, weddings, funerals, our own dates, coming home from work pretty much everuthing. If we were together I'd have to try and bother him to be on time, but we'd always be late and it was embarassing. His moods started to become crazy, he loved me one minute, hated me another and had a baseline level of irritation all the time. Eventually he started taking it out on me a bit, yelling at me for the smallest things and treating me kind of badly. He started to get very indecisive and not know what he wanted anymore. If we went out, he'd complain that he wanted to be at home relaxing. If we were at home relaxing, he'd complain he wanted to be out. Movies and TV that he loved before, he suddenly hated and the opposite, but wouldn't admit that it had happened and would convince me he always loved/hated it. He started telling me he was empty inside and he didn't know if he wanted to be with me anymore, but that would change the next day. After a few years he developed anger issues, even tried to join a fight one time and started punching walls, doors and throwing things. He started to have delusions about how everyone hated him, found him ugly and that people purposely avoided touching him when giving him change and that they made faces of disgust. All his friends only were friends with him out of pity. He started to become very aggressive and do dangerous things, like sleeping outside, leaving the house without telling anyone without his wallet, keys or phone and driving super recklessly. Sometimes he wouldn't come home and I'd have to ask people where he was. He seemed constantly depressed and miserable. We fought all the time for hours over these things. I put my foot down and said he needed therapy and that I'm moving out. He agreed to go and I moved out to save my own mental health. He went for a bit, but it became less and now he's not going. He had a pretty bad childhood, with an extremely overbearing mentally ill mother and alcoholic father. I think he's severely mentally ill. I am still moves out and don't know ehat to do, he denies that there is anything wrong. Help!
