Don't run away.

Press charges for harrassment or battery or rape or whatever applies. You don't have to prove it with bruises.

Tell him that every time he comes now you will call the police. Then do just that. Don't have any conversation with him; don't talk to him at all except to say "I am calling the police." Tell the police whatever you have to to get them to come and especially that you are afraid for your safety.

I don't know what an AVO is but it sounds like a restraining order. That is a very civil solution, but people like this aren't civil so it doesn't help as it should.

Is there someone who could come and stay with you while you get through this so you don't have to be alone?

Please let us know how you are
