That is basically my story. My daughters are 2 and 6. I left in September. He can't keep a job or a place to live, so he is on my door step regularly. Am I glad I left? YES! It was the best thing I ever did. My A is a mean drunk also, but not physically abusive. All love for him was lost years ago, and I thought I could stick it out for the kids. As it turns out, the kids shouldn't have to stick it out. Funny thing, my 6 year old didn't even question why daddy wasn't coming with to the new house. She already knew. Staying around will probably do more harm than good. In many ways I still feel stuck. But I am in a much better place for having taken that step. Good luck to you.
