My soon to be ex is trying to take a car we bought together?

My soon to be ex boyfreind is very abusive and thats why I want to end our relationship.We bought a car in Feb.2011, he has abetter job so hi name is on the loan contract but not on the title.My name is the only one on the title and the plates and insurance. I told him he could buy me out but he refuses, saying he's taking the car and not giving me a dime. As I said he is very abusive and if I argue about it I'll end up getting punched and berated. Can he take my car? What can I do short of having arrested for hitting me. Please Help!! I have never been so miserable in my life and I need to know how to fix this without getting a black eye.
