I'm not sure about the laws in Fla, but I know here in MA there are things your lawyer could do to protect you.
There are steps that can be taken to protect your credit so he can't ruin you financially. In MA, once you file for divorce there is an automatic restraining order put in place to prevent either spouse from draining bank accounts as your AH did, or from incurring unnecessary debt.
Again, I'm not sure of the laws in your state, but AH has legal obligations toward the children, and probably towards you depending on the length of your marriage. Usually if you make significantly less than your spouse, you can get some type of spousal maintenance til you get back on your feet, especially if you have been the primary caregiver for your children.
Let us know what your lawyer says! I've got you in my prayers!
