Scooby, Have you considered taking a bit of cash out of the account to start a nest egg for you and the kids? $6,000 is quite a bit of money to be spending in one week.
Don't be afraid to do what you need to do in order to protect your assets and your kids. Start by contacting a lawyer and finding out what you need to do before all of the money is gone and you and the kids are left w/nothing.
Don't put this off another day. Monday morning, first thing, search for a lawyer and make an appointment w/one that has a free consultation.
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.
