Hi. I(18f) have a friend(18m) who lives down the street, we'll call him Bob. For context, I broke up with my ex boyfriend over a year ago. He seemed super nice but he ended up not being the greatest. When I broke up with my ex it happened to be a week before his birthday. I know it was wrong but I did it over text, I was way too uncomfortable being around him to do it in person. After a couple of months he tried texting me like we were all good and things ended in an argument. He had sent a screenshot of a text my cousin had me send telling him to "kindly fuck off" to his friend group chat of about 50 people. In said friend group I have some friends, multiple of them approached me and wouldn't stop bugging me and joking how I'm being not a good person for using bad language. We haven't talked since and I blocked and deleted his number. After I told my friends, Bob wouldn't stop calling me a monster publicly and bringing my ex up a lot. He got mad at me for saying I don't like my ex because he says he "seemed nice". He only met him for about 5 minutes and my ex didn't even say much to him so I finally decided to open up about why I don't like him and why I broke up with him. I told him about how my ex couldn't take no as an answer, he was uncomfortablely touchy and constantly needed to be touching me, he multiple times wouldn't leave when I told him too, and a lot of other things. I told myself that I was just being weird because I come from a family where we don't hug or anything, we honestly don't even say I love you. But my pushing point was when I found out he and most of his friends would harass and bully his last ex. When I told him to stop and leave her alone he, and I quote, "oh, it's (her name), she doesn't have a soul" and brushed me off. He still continues to call me a monster despite him agreeing that it was good to break up with him.

Fast forward to now, Bob about 3&1/2 months ago broke things off with his girlfriend due to problems with her dad hating him. I don't like getting involved with his love life because he is basically always dating 5 girls at a time despite HAVING A GIRLFRIEND and saying he is so in love her and have been since the first date. He never lets me meet his girlfriend, it changes so much it's hard to find the current one before things end between them. There have been times where I'm worried he's going to ask me out cause he tries dating every girl he is friends with or is drawn to. He loves to dump his relationship problems on me and he was telling about how his girlfriend from 3&1/2 months ago thinks he's a monster. I jokingly told him that we can both be monsters and join the club, he got super mad at me and told me I am actually a monster for what I did but he wasn't. I tolded him I think my ex is stocking me at lunch and he told me that his ex is stocking him. The thing is she happens to be near him always because he has classes with her and he hangs out with her friends and his new girlfriend. So I don't think she is but I didn't say anything, he told me that it must be a coincidence that my ex always it circling where I am at lunch. I have tried moving places but he always finds me and walks in circles around the area I am like a vulture. I again told him to join the club of being a monster and left for my next class. He now is avoiding me and I'm kinda glad, I'm going to distance myself from him and that makes it easier. So AITA?
