I am in the same situation although we have been together for almost 10 years, married 6. Three months ago I found out he started drinking again. I have almost 10 years sober and he would have had 10 years sober. This sucks and I want out. Thank God I was smart enough not to have kids with him. I could not imagine. Mine does the same thing- keeps me up half the night and I have to get up and go to work. I am scared as heck to tell him I want out, but I know this is the best thing for me. I know I will be fine alone and will one day (maybe) find someone special who will treat me with the respect I deserve. You will too.
