Hon, I think most everyone here has had experience of this type at one time or another. Now I know I haven't read any of your other posts, so I feel that I am coming on in the middle of this, but I feel fairly sure that you are attempting to start your own life away from him, or trying to decide if that is what you want. The one thing that you must realize is that you cannot control his addiction or his using (drinking). You cannot control is he lives or dies. That is not within your power to "save" him from the bottle or himself. That power is only within "him" and his HP (God or whatever).
You didn't cause it, you can't control it, you can't cure it.
What would be good for you to do is to get help for yourself. You may not be an addict, but your life has been affected by one or maybe there's more than one in your life. Getting help for yourself and learning not to get caught up in the drama of an addict is the best thing you can do for YOU.
