Co-signed Vehicle Loan

[aviv]

What is the name of your state (only U.S. law)? Ohio

I am the co-signer on a loan from American Honda Finance. My ex-boyfriend and I signed a loan for a car and both of our names are on the title. We had a falling out, and he missed several payments, destroying my credit. I have asked him to refinance the car in his name or find another co-signer, and he has agreed to do so, however we are not on good terms and it doesn't appear that he's made any effort to take me off the loan. Is there any way that I can protect my credit? I want my name off the title of the car and off of the loan. I don't have possession of the vehicle, I've never driven it. I made the initial down payment and he paid me back. He misses payments and tells me he can't afford to make them occasionally. He recently purchased a motorcycle (paid in full) and went on a vacation to Jamaica.

Is there ANY way that I can detach myself from this vehicle and loan? Please help.
