<human>: I have been friends with a guy at University for three years who's always been a bit creepy around women.

I always thought this was him just being socially oblivious as he's the type who lies about everything to make himself seem better but doesn't realize everyone can see through it.
Plus I felt a bit bad because I was one of his few friends.

Recently I bought him over to my apartment and my roommate recognize him as the stalker of his ex girlfriend, and that he wasn't comfortable with him ever coming to the apartment.

I believe my roommate 100% because of how well I know him and how my friend acts around women.

I want to completely break off the friendship because I don't want to be friends with someone who acts like this, but he's been a pretty good friend to me across the time we've known each other plus he's the type who really can't take a hint when being rejected. I probably won't see him much because I don't currently we don't currently have many classes in common.

I'm wondering how to break off the friendship, It's going to be hard because he's the type who really can't take a hint.

Give me the gist of the text in a nutshell
<bot>: Thought my friend was just socially oblivious, turns out he;s a full blown stalker, wondering how to break off the friendship.
