Looking for someones advice, who has been in a marrige with an alcoholic husband?

About a month and a half ago, I took my children, what little stuff I could fit on the greyhound , and myself, and moved out of my husbands apartment. He had too many people staying in a two bedroom, and called me cold hearted because I wanted them out. (Our kids had to share a bedroom with us.) My husband drinks alcohol if not everyday, than faithfully every weekend. He becomes verbally, emotionally, and sometimes physically abusive towards me while he's drinking. And he thinks about nothing but himself. On a good day, he really is a genuinely good person, but all that changes when he is drunk. He bullies other people and I am so scared that one day he will pick the wrong person and they are going to seriously hurt him or worse. I had to remove me and the kids from that environment, and thought that once we were away from him things would get better. But now I have sunken into a depression and am finding it harder to succeed. if someone has been there any input would help
