I'm going to break things off with a guy that freaked me out.
What did he do?
He's just crazy and weird, and he makes me uncomfortable.
You should never stay in a relationship that you don't want. It's better to just separate entirely.
But I'm going to look like the bad guy if I do that. I hate him and he's going to come out looking like the good guy.
If you're worried about how other people will perceive you after breaking up with him, just explain to them what happened. I'm sure they would be understanding and supportive if you tell them how he made you feel.
