I have read your posts and felt for you, but didn't have much advice really.
It is rally hard when the two people in a marriage have different attitudes to money and how to handle it. And it really is horrible when one gets stuck with the fallout of the other's bad handling of it.
Your H sounds very angry and immature (now where have we seen that before?? ) and is basically blackmailing you.
Personally I would stand your ground and not say things that you don't feel or agree with. But if your H wants a D and insists on it, just say "I can see what you want, and I am powerless to stop you if that's what you want. It is not what I want, but I will not fight you over it. Go ahead and do what you want."
I think you need to take steps to protect yourself financially, because in his state of mind he could do even more damage to your interests, like worsen your credit rating. You need to draw your boundaries with things like that, even if you hope for an eventual reconciliation. If you do reconcile, he will THANK you for that!
