I think I will let others respond because I haven't been in your exact situation. But I want you to know that I sympathize and do understand how ones feelings could be hard to hide when faced with a situation involving alcohol.
Yes there are people whose lives dont revolve around drugs and alcohol. My advice if you haven't done it yet is to join Al Anon and work the steps - it will help you immensely to recover from your A and the other A's in your life.
Congrats on leaving, you deserve a happy life and you will have it. ((((HUGS)))) Red.
