Boy, do I know that feeling! But don't wallow in it...you can feel shameful and embarrassed and disappointed today while you don't drink, and then tomorrow when you don't drink, you can feel less shameful and embarrassed and disappointed, and then the next day when you don't drink, etc...
I can't imagine staying sober with alcohol in my house; I think you should hug your wife really hard, and take her up on her offer of supportive abstinence. She sounds like a keeper!
