Drained;
Ask your lawyer if there are any other ways to protect your financial interests.
I know here in RI, they can post in the newspaper that one spouse is not responsible for the financial issues of another. But, that's only for future debts; not present ones. And if you own a house, it may be another issue altogether. I don't know Fl law at all. Each state can put their own laws into effect, and you need someone who is familiar with them.
Please be sure to take care of yourself and your children. You cannot fix him.
Shalom!
