Go back further than 2 years on the tax documents. In fact go back at least two years before BD1 ... You're looking for financial trends, etc. Please consider hiring a forensic accountant. I firmly believe you will need one as I do not trust your H at all.

It's best he moves out quickly. Lock down all assets as have been noted by other posters.

This is now a business that is dissolving. Separate the emotion out of it as much as you can.

Focus on what YOU want and what you think you'll need moving forward. Protect your boys in case he decides to create family #2 - or #3 or #4 - the best deal is the one you're going to negotiate for your kids and yourself.

He has given you a great gift by breaking the stalemate. MOVE ON IT.

"Someone I loved once gave me
A box full of darkness.
It took me years to understand,
That this too, was a gift."
