I didn't do something that my bf wanted me to do (sexually) and then he told my brother about it (ack!). He wasn't a fan of the word 'no'.

When I broke up with him he told his best friend that he felt numb all the time and the only thing that made him feel anything was when he thought about hurting me. He told me that one time I had said no (we were at a party and there were other people around) and he didn't listen, he saw the fear and concern in my eyes and it turned him on. Any time I talked to him, he would tell his best friend about the convo and how I was behaving exactly as he wanted me to so that he could lure me in and start his big plan to hurt me.

His best friend stopped being friends with him (good call). Ex kept contacting me so we could meet up so that he could "pay me back" all the money I spent on him and he just wanted to "give me what I deserve". Proud of my past self for not meeting him. He would contact me once every 6-12 months for a few years just to let me know he was still around and still thinking about me.

Brother still wanted to be friends with him. When I finally called the cops on my ex I gave my brother an ultimatum. I couldn't have people in my life that were chummy with those that fantasized about hurting me and openly admitted it. He eventually stopped being friends with my ex but I don't think our relationship has ever recovered from that. He would always say the big brother thing that he would hurt anyone that hurt me but when it came down to it, when it cost him something to stick up for me, he had to be forced into it. I know better now.
