Glenda,
It sounds like you have tried really hard here and I sympathize with you. I also agree that it's the attitude more than the actual money that's the root of why you're upset. I think you would feel totally different if you felt he was invested in paying off the debt and that you were working better as a team on it. Plus, it's hard to live in such a high cost area. The basics are expensive!
I guess the only thing I can think of is selling the car (even though it's financed, you can sell it to pay off the lien can't you?) and buying something either with cash from the sale or just something MUCH cheaper. Like a 2003 Saturn or something (just as an example, I drove a cheap ass Saturn all of college and it was good to me). Then whatever you're saving each month on a cheaper car could go toward the CC debt? I don't know.
I hope he is successful in calling the card company and lowering the rate! That would be a big help.
HUGS to you my dear!
