An ex-addict who drinks is not what I would call "clean" as alcohol is a class IV Narcotic. Different substance. My opinion. Someone playing with fire.....
Focus on you. Maybe you'll be able to move forward and stay stopped. Only time will tell. I know you can do it again! I side with the therapist. If you get a resentment, well, you know what to do with those, if you work the steps on it....
I wish you well!
Hugs, love, & peace,
