If you can buy him out of the house for $5,000, DO IT! (Assuming you can afford to stay in the house yourself and want to stay.) It's not worth it to stay involved with him in the house, ie as in you sell after the kids are grown etc - too messy.
Make sure he signs something to agree to pay his part of college costs - may be worthless paper, but saee if he will.
Child support is by formula,right? That should be one thing you DON'T have to argue about. If he bitches just show him the guidelines.
Get as much as you can for yourself TODAY rather than in future obligations; sometimes these guys go right down the toilet and you can't get blood from a stone.
Business, business, business - keep ALL the emotional stuff out of these negotiations.
PS - I suspect, despite his apparent haste to get this done, your H actually is unsure and dragging his heels - hence he may pick stupid, unnecessary things to argue over. Barb's H fought over the artificial plants!!!! Don't get sucked into losing focus. He haasn't thought this through and is shocked that he can't just seamlessly leave his life and spend all his money on himself.
