no lawyer will take my case for lack of money!!!!

I have been separated for the last 6 months. After my husband OD he moved out. He's had drug problem since 2003 that I know of. He went to rehanb twice. He was very aggressive, he even shot a gun and pretended to be dead on the grass. This happened last year at 2am. He has deposited empty envelopes in the joint checking acct and today I was told this acct will be closed. 

Because I was afraid for my children's safety I sent them to my mom's. He knows, and he approved. I went during the summer for 3 weeks to see them and when I came back, he said I needed to move out, he will change the locks and I will no longer get his check to pay the bills.

we've been married 11 years and I was a stay at home mom. I have never worked either. I started going to school 2 years ago because I wanted to be able to get a good job. I have 2 kids to think of.

Is there something I can do to make him pay the house bills, the mortgage? I asked to sign so we can sell the house and he doesnt want to. I need to get out of this loan but I cant force him to sign. He and his father are using scare tactics and bullying me out of here. His father had said he will put a lien on the house for $80,000. The reason I think he could do it is because where he works theres notaries, he can have someone sign my name and in order to get to show all this is not true, it will cost so much money and me having no money, who is going to take a case like this?

my father in law help my husband start a businees 10 yrs agoa and in december 2007 the company merge to a different one and now the only owner is my father in law. this happened while we were living together and i was never informed of this. 

I need to be able to relocate, but fl law isnt too helpful in this matters. My husband has aggressive issues besides his drug addiction, and it seems enough to be able to get my daughter protected, it doesnt work that way from what a few lawyers had said to me. And because of all thats happened, being so painful, we need a fresh start. I need to sell the house, to get approval for relocation. 

is there something that I can do?
