My AH did follow a program, at least outwardly - lots of therapy, active in AA, sponsor, etc etc. And he relapsed after 3 years and is currently on a bender. I'm filing for divorce after 5 years of being legally separated but hoping this will not happen again. We have a 6 y/o boy and he's a good dad when sober, but what good does that do if he can't stay sober.
Following or appearing to follow a program isn't enough. Relapses happen and will always be a risk. I hope you find peace in whatever decision you make.
