Jala,
Hang in there girl! We've all been there and feel your anxiety. My AH has been dry (I dont consider him sober yet) for 8 weeks. I did the same thing you did for 16 years. We separated 6 months ago and I was a mess. Went to Al-anon and got codepedant counseling.
I found that when I finally didnt give a sh** what he did and just took care of myself, he responded differently. I'm not too confident he'll stick with it, it's too soon. But I dont ask if he drank (you can always tell anyway) or what he's up to. I set my boundary (no alcohol) and he knows if he drinks, it's over, simple as that. No more crazy life for me, I've had enough.
When I finally let go (yes, it's very hard) and gave it over to God and said "Take this off me and do what you will with it", I began to feel better. I had peace and was able to sleep at night. Now if things dont work out, I think I can move on without falling apart.
Sending you my strength vibes Jala. You can do it! You are worth it!
