I agree with every wise word that Smoke said.
There are very few guarantees in life, and recovery does not come with a money-back warranty. The best of them can fail and the worst of them can make it, it's not how bad they were as A's, it's how willing and diligent they are at maintaining sobriety. And that can change from day to day.
My son is an addict, presently in a long term program. Over the years I have seen him maintain a good amount of time (years) and relapse when everything seemed wonderful for him and when he seemed to be working a program. And I have seen him stay clean through some terrible crisis.
So how they appear, how they handle situations in their life is only part of it. It truly is a one-day-at-a-time process.
My suggestion is to work diligently at your program, which will give you the strength and courage to do what is right for you, at any time.
Sending hugs and prayers for you and your family, that each day of sobriety can be seen a gift to you.
Hugs
