So close, yet so far

I actually thought we had a breakthrough, me and the ol' stbx. When I dropped off my daughter tonight, she asked if I wanted to talk. I didn't really, but was feeling pretty good, so I agreed to talk.  She told me she was going to fire her lawyer, that she didn't want to spend the money. She said she would agree to anything I want, that she doesn't want to stress or fight.  (Of course we've had this same discussion several times before, they never end well).  So she told me that she would rather move out into a rented apt or condo, and that when she moves out I can move back in the house, to put it up for sale.  She agreed to sell the house. She agreed to the 50/50 custody arrangement with the children.  She agreed to splitting the bank accounts.  She wanted a few of the household things that I wanted, but no biggie, definately not a deal breaker. The only thing she would not agree to is splitting the marital debt.  Which we don't have any of, except for my car.  We recently paid off her car through a house refi so she would have no payments. I maintain that when we sell the house we should then pay off my car, so we will be on equal footing. With paying alimony, if I have to assume the entire car cost, it will put me at a huge disadvantage in quality of living.  I do not wish to take advantage of my children's mother, I want her to have a decent life, and be able to be happy, and help the kids be happy.  But I feel like she is again trying to take advantage of me, this time to the tune of the $10K debt.  Am I off base here? Or am I right in my thinking?
