@matigo wow, dude, that's fucked.
In my case, she closed the rest of the accounts but one of the shared accounts (the one my paycheck went into). I used that account to pay the filing fee for the divorce, but haven't used it since.
Hopefully she hasn't frozen your credit like mine did. Made it very difficult to get a bank account until I got it unfrozen. It was a race against time to get a new bank account open and call my employer to get my paycheck deposited into the new account.
Good luck, my friend. Sounds like you're in for a battle.
