Be very, very careful here. What I sense from what you are saying is that he wants to be divorced while you stay very much married. He wants to date, do what he wants, have no responsibilities....while you worry and manage and make sure financials are in order.
Eff that. (Yeah, I have some strong opinions on that attitude).
Please keep a close eye on shared financials like credit cards, bank accounts, loans, etc. For example, in the midst of my divorce I found out that my XAH had gotten a credit card account but got cards for both of us. I, of course, never saw the card. I think the plan was to run up a bunch of debt on it and then make me pay for half when the time came. But when I found out I immediately cancelled my name off the account and when we divorced he had to take all the credit card debt.
Also, he cashed out his retirement even though I probably would have been entitled to half.
Might be a good idea to put a fraud warning on your credit report so nothing can be opened or proceed without you being contacted directly.
Just sayin'....
