It's a tough sitch to watch & know and accept that it is beyond your control. But did you say that the sponsor was someone with 30 years sobriety and who knew Bill W? (Bill W was the creator of AA and is very well respected for those of you unfamiliar with AA, he's the "guru")
That's a pretty serious "credential" if you know what I mean. Why'd your h pick him as his sponsor? And they did not support the reconciliation yet? Is that correct? Or at all? I'm assuming the former and that really is standard. They've seen too many relapses and failed m's that might have been avoided, had the recovering person simply taken it more slowly. How long did your h drink and how long has he been sober?
Well in any event it sucks to have a sponsor "fire" you. That's a bummer. But maybe your h will react more with the next one. If not, I'd be very concerned. I have only known one sponsor to fire someone and never without a warning. I think your h probably knew it was coming. Is it possible he wants an easier sponsor who won't hold him as accountable? Just asking.
I know that you see changes in him and want to believe all is well, while still knowing that it is a long road. I am just reminding you that there are those with a lot more personal experience, who know what tends not to work so well. They just don't want him to repeat their mistakes. Make sense? We all want the best for his recovery and your M. Good luck J-
