Cut off all contact with him block him from sending you messages. Then give him a warning not to contact you again. Then if he does call the law. It's that simple.

Im sorry but he is an ass. Saying that he doesn't need a gf and shows up with one its not nice, he could just have dumped you, it happens. I think He just wants sex and even though I liked him, I would put myself first. You can find someone that really wants to be with you... Don't trust this guy.
