If he's moving out, you need to take half of the funds from the accounts and place them in your new separate account. If you don't do this, he will most likely take all of the funds or leave you w/just a little bit left in the account. I think it's time that you make a spreadsheet that indicates what funds are coming in each month and what is going out on household expenses and then, hopefully, come to an agreement on what he will pay in child custody and the household.
Do not believe anything he promises/tells you. They like to tell us what we want to hear and then they do the exact opposite in most cases. You will now need to look at your situation as a business deal gone south and protect yourself, your children and your assets as much as possible.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
