/ot/ - off-topic

So I'm youngish and not very experienced in relationships, only been in 3 very short-term ones and got out of one just over 2 months ago.

He got a new 'girlfriend' very soon, a month maybe, following the breakup (a rebound?) who a few trusted sources have told me is ugly as sin and resembles Nick Park and is also about 6 foot tall, long face, 'nose like a beak' to quote one friend, but he hasn't put set it on facebook like he did with his last serious rs. I also never see them together and he keeps bragging about how he 'fucked' her when he can barely get a semi becasue of his drug use.

Anyway, we have frees together and I'm in his friendship crowd so we see a lot of each other still I've completely ignored him and not even looked at him (except accidentally when i look away in 0.3 sec). He keeps trying to make conversation with me/talk to me/get my attention/ask me direct questions. The more i ignore him, the more he tries. He uses subtle insults in front of me sometimes, e.g. suggesting I have yeast infection, will be a benefit mum.I guess they're supposed to be jokes or get my attention.

He also butts in to my conversations with others. I was offering some kind of prescription to our friend and he butts in and says 'thats fucking lit!!' and when im finished says 'no thanks' even though i didnt fucking offer them to him.

I do not understand why he wants my attention so darn badly. I haven't been giving it to him at all and haven't spoken to him once.

This attention seeking started about 1 week into me ignoring him.

I've made up this fake boyfriend that I've been telling my friends about in front of him so that he'll step back, but it's only had little effect.

What does he want? Does he want to still be friends? I miss him terribly and it breaks my heart when he talked about how he 'fucked' his new gf (yh right with ur impotent penis). But I don't want to talk to him for a while as he's hurt me and I'm trying to move on.

Can anyone give an explanation for his behaviour? Any perspective or insight from a relatively expereinced male/female/everything in between would be appreciated.

How should I respond? I try to spend as little time near him as possible but he tries to talk to me at most opporunities.

Do I keep ignoring him? tell him to fuck off? Confront him about his behaviour?

(Also: im close with his best friends but they dont talk about feelings/girls so they cant give any info, its kinda sad)
