As someone in recovery I can tell you a very basic truth, you are doing the absolute right thing. You CANNOT help him. Addicts/alcoholics have to rescue themselves, no one else can rescue them. It's when they realize that they begin to recover and not before.

Since he has a history of violence, is he on probation? Alot of times, there are pretty tight restrictions in place on who they can associate with and even on drinking/drugging. If he is, do you know who his probation officer is? If you don't, contact your local police department and explain the situation.

If you call or go to a shelter, I would guess they might be able to point you to the correct resources for someone in your position. Legal Aid or something. You should be able to get at least a temporary restraining order pretty quickly and that should get you back in the house with your kids and him ordered to keep his distance. You can actually go to court and obtain one yourself. Check on the web for what you need to do in your state. It is usually pretty basic.

Also, you may want to see if you can find an Al-anon meeting. Just call Alcoholics Anonymous (directory assistance or your phone book will have the number) if you can't find them directly -- they will know who to call. These are meetings for partners/family/friends of alcoholics. These groups meet to share and work on their own issues (deal with your own problems instead of the alcoholic's) so just frankly speak about your situation. I guarantee you -- people there have either been in your situation or have heard the same story before and will have some good advice for you. Some will come up to you after the meeting and offer help. It ALWAYS happens. You will be amazed how NOT alone you are. They will offer phone numbers. You will not believe it until you experience it.

Good luck. You really are not alone. But please remember that so long as he is drinking, you cannot trust him at all. It is truly sad, but you cannot believe him. He cannot admit to himself that he is out of control yet, so you cannot trust it when he says he will change. You need to believe it only when he DOES it and does it for a long time. Please protect yourself, you babies, and your heart.
