What would you do if someone was avoiding you?

He probably has a mental problem and is trying to control himself. The fact that he got that angry means that he wasn't someone you would really want in your life in the first place, and it sounds like he probably would have tried to rape you if he didn't have you get out of the house immediately. He doesn't want those feelings to resurface, so he just avoids you. Another red flag is that he doesn't have friends. I am pretty sure that he has some sort of problem, and it's none of your concern, just keep moving on with your life and try to stay away from him.
