<prompt> Human: My girlfriend and I recently bought her a car. Well, I fucked up by helping her finance it. Now Im wanting to leave her. Long story, but shes literally crazy. Anyways, my name is first on the loan with her as a co-buyer. My credit is fine but hers is meh. I dont want to sell the car and leave her without a vehicle. She has kids. I dont think that I could afford to pay the note on it if she were to default on the loan in retaliation after the breakup. I want to get out from under it, but Im not sure how. Any suggestions would be great. I just wish I was dealing with a reasonable person here, but her insanity shows itself more every day. Theres no telling how shell react. I know I was stupid to sign on the car in the first place but whats done is done.  <response>: Too bad buddy. Youre stuck with this. This is why its primarily never a good idea to co-sign.
