That dude gave your chick ex, obviously he was gonna try to make a move once it kicked in. Calling the cops won't do shit. I say beat that dudes ass, haven't you ever heard the quote " It's not the size of the dog in the fight but the size of the fight in the dog?" I went to school with dudes like that, doesn't matter how big you think they are, dude was feed with a silverspoon in his mouth, trust me he can't hold his own.
