My RABH said something the otherday that your post reminded me of...something about "4 slips" during the early recovery period is about average. Your right sometimes good things come out of the worst mistakes! Recovery is more about the emotional sobriety part. When working on that part the urge goes away. AA says the booze is but a symptom. So good for you guys! Progress not perfection!
The "slips" early on scared me, but now that I see such positive changes in RABF personality, i think a slip wouldnt be so devestating. I get how hard he is working the program. So as long as he recognizes the mistake and took it seriously...i wouldnt worry myself too much. There is a learning curve after all! And btw...my rabf didnt/couldnt "finish the job" either because he knew it was wrong!
