My b/f gets really aggressive when he's mad, so I'm afraid to break up with him?

To break up with him, go on a "date" to a place with a lot of people. Break up with him there, and make sure a bunch of people are around you. If he gets mad/violent, they'll keep him from hurting you. After you break up, try to be around your friends a lot so he knows he can't hurt you without other people seeing. It kinda sucks that you sexted him, though. I wouldn't say anything about them, just hope he forgot.
