I haven't read your whole thread but what I did read is not just sad but also very frustrating. Your husband is a very unhappy little man but somehow it makes him feel better to take it out on you. He must feel that he has no control in other areas of his life so yelling at you (because he can) releases some of that self-loething. No matter how you cut it it sucks! You on the other hand did a great job in not playing into his tantrum and believe me I know that that's not as easy as you make it look.
Let me ask you this. When husband first left he took all of the money with him. Oh I had my paycheck but I was using it to pay for my kids daily expenses. My lawyer filed a petion with the court for husband to pay the retainer and it worked. He was ordered to pay. I don't know about the divorce laws in Florida, but maybe you can ask if there is any such thing provided under the Forida law.
