Alcohol Has Ruined My Marriage

My husband is an alcoholic. At the beginning of our relationship his alcoholism was really bad, and I can admit he has gotten better over the years but he hasn't completley let go and he always falls back. We have 2 daughters together both under 3 years, and he has another daughter almost 13 that neither me nor my children have ever met. He lost his visiting rights to see her after getting his 3rd DUI at the beginning of our relationship together. It's been an extreme uphill battle ever since. Myself coming out of a terrible physically and emotionally abusive relationship before him, I was already mentally depressed. I am to the point now where I am so broken I feel like I am nothing. All of the things he has ruined because of alcohol would create a huge list. One of the big ones that still wears on me is through the 12 hours of my youngest daughters birth he was absolutely plastered the entire time and it hurt me so bad, and still does. He is emotionally abusive sometimes physical but it is rare. He has left my children home alone before to get more alcohol. He is a liar and deceitful. He has made no attempt to better himself by getting his license back and his oldest daughter. This all should have been it for me but I really dont know how to leave. I am a stay at home mom so I have nothing to support me and my girls if we were to go off alone. No savings, no job, nothing. I love him but I can't do this anymore or to my babies. I need some advice, some support...something to help me really push into this change that's been needed for a long time.

Thank you...
