Good for you for not jumping at the chance to go out with him. I could totally see myself canceling my plans and going out with my H. So totally good for you!
I would be really ticked about the car payment. Heck, I am a little ticked about my H not paying his student loan and my name isn't connected to that. I think you need to really talk to him about this and let him know that paying part of it isn't a choice. If he can't pay the whole amount then he needs to sell the car.
My gosh, the comments your H made about that car totally sounds like mine!!!
