A,
I am sorry for all you are going through, for so very long. Its just not fun!! Sounds like you have finally hit your rock bottom. Addicts and codies both can hit this. I think that getting out of the home is a great idea. It will give you time and clarity on what you really want in life. You have to remember, he doesn't have a problem with his drinking, you do, so it isn't his problem to fix, it is yours.
Own this reality. You have tolerated his bs for a very long time. He is not going to change so you either live with it as you have, till you can't any longer. Take the time away and find out that you are capable of,to live on your own and not be under such anxiety living with an addict. You deserve peace. Our lives on earth are very short, and wasting it on living with an addict waiting for his sobriety could take forever. (he actually could live longer then you)
You are going to have many emotions by him. Anger - Guilt - Apologies - promises. Stand strong and tell him actions speak louder then words. And that action is Sobriety- and working a program.
Keep moving forward and see where it goes. hugs!!
