I'm happy to read that your bone scan indicates that you are healing and fighting the war on your illness.

As for your h, there's nothing you can do about his behavior, but your lawyer can contact his lawyer about the funds. Since the children live in the home, those "unpaid" expenses will affect their living conditions if the mortgage, electric, water, etc. aren't paid. I honestly do not think that any contact w/your h about the funds will guilt him enough to put the money back into the account.

Instruct your lawyer to take this matter to his lawyer. Do not put this off.

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.
