Hi Reader
You've come to the right place, that's for sure.
I hate to be the bearer of bad news, but usually if the A does it for any other reason, but for him/herself, chances are great that he will relapse. And/or get angry with you in the future and when you have an argument, he could say things like "I did this for you! For our marraige, what more do you want from me?"
I've only known ONE man to stay sober after his wife told him to sober up or she's leaving.
The rest just do the "right" things and say the "right" things to buy more time with you. Manipulation is a biggee with A's. They can tell a lie better than the truth. And,..then forget the truth because they've lied so much to everyone.
Are you going to Al anon? It's a great support system. I wouldn't wait for him to get his life together........get on with your's. If he stays sober.......great! But, if not...stick to your guns and walk away like you said you would or it'll just repeat it's self over and over and that'll kill not only him, but you,too and life's too short.
Actions speak SO much louder than words!
I'm sorry, hon!
