I'm really confused on what is happening here on so many levels.
Obviously you are an alcoholic. You admit that. You say you keep trying and why can't your husband see that your are SO committed, but you you fall off every 7-10 days. Doesn't sound sincere to me. And hey....I'm an alkie too so I understand.
You don't want a divorce, but if you get mad you print out divorce papers. It really seems like you two just go back and forth and argue and try and one up each other. Sad sad situation. He doesn't really seem to like you much and whether this has to do with the alcoholism or something else you won't really know until you STOP drinking for good. If he behaves this way after 120+ days of not drinking and you start going to AA or use another program, well I gotta say you gave it your best shot.
I wish you the best, but I see a lot of I'm not to blame in this because I am TRYING. That's not enough.
And is he hiding your keys because he doesn't want you to buy alcohol? Drive drunk? Drive with your kids. He must have reasons. Just my opinion on this.
