I think it depends on how 'done' you were before they tried to get sober.
I was pretty done before rehab, much less the relapse. I just didn't have enough recovery/strength to be give myself permission to be done. The relapse was a line in the sand.
Had that played out years before (him going to rehab) I would have probably stuck out a couple relapses.
I work towards a future where I don't need any permission lines. That I give myself permission to do what is right for me, because it is right or me.
