desperate, confuse!!!!

im separated from my husband since feb 09...he has a drug addiction. he also cheated with some woman in ny. for all this time i was getting his check to pay the bills. i was hoping i could get over the pain and take him back but im too hurt to forgive now.besides his drug addiction, he has shot a gun and pretended he was dead. he torn down a door in the house because i didnt give him 60$...he was very aggressive and emotional and verbally abusive. for 11 yrs of marriage and taking all of this from him i feel im done with this relationship. i should be crazy to stay. its too much abuse, too many drugs, too many lies.
today he came over to tell me i need to move out of the house. he says his fathers said he would continue to make house payments if im not here. there was a business before, but his father took over. since then my husband gets checks from that company but now he says his fathers is stopping that too. but the only way he will pay for the house is if im not here.my name is in the deed too, so if they dont pay my credit is ruin. my husband knows i care about that. last year he used my credit card and spent 10,000$ i paid for it because it was in my credit, now i regret it. 
my daughter is out of the country with my family. she is going to school and doing great. he agreed to her moving for the school year. she is 10 yrs old. im going to see her soon. and i was just there with here. my 18 year old son is flying soon to work for my dad and help me with his sister while i sort things out here. i hate being away from my kids but i feel i have no choice. they are better there than here for now.with no money coming in from him, i wont be able to pay for groceries, gas, house bills etc. over there they can eat. i feel they are safer there.
i need some advice. i feel lost and maybe even scared...my aunt thinks he has another woman and it makes sense now that i think about it. he took money from my bank acct and left me with minus 300. then he said he was kidnapped for 3 days and his phone stolen the last day. if his parents took this so lightly, it has to mean that he has another woman. i dont understand how can they be so calm if he was kidnapped. and why no one file a report???
