Classic technique (pay off my car) trying to get little chunks of money from you, all to support your girls. Tell her to propose it in the settlement.
She would want it paid off and then leave the NPV of the cars out of the settlement, as if she was doing you a favor by "giving you" the new car while she took the older one. But in reality hers would be an asset and yours would be mostly debt.
I can't figure out how she says this stuff to you with a straight face:
W: My lawyer says everything is waiting on you!
H: Yup.
W: Well why don't you get moving?
H: Sorry. My concern is the welfare of my children, not the timetable for your love life.
W: If you cared about the kids, you'd pay off my car.
H: If you are planning on leaving, then you'd better get used to paying your own way. If the kids are too much of a burden for you, I'll take them full time.
W: If you were any kind of a man, you'd move out until the divorce is final.
H: Do you mean the kind of a man that has an affair with a married woman and abandons his wife and children? You're right that I'm not that kind of man. Lucky for you, you've found one.
