That’s really great to hear.
Is he violent in any way when he drinks ? Is there a risk of violence to you or your children ? This would be my main worry re: leaving right now, obviously you can still support him from afar. I’d say just focus on tonight and then you’ll see how things go.
At this stage it’s fingers crossed the group will encourage him to go to rehab. They would I imagine know plenty, and they will be able to introduce him to people who have succeeded.
Do you know which group it is by any chance ? You might just want to ring them, to know their general approach, advice for yourself. You can just say you want to be on the same page. I doubt they’d accept names (well, I don’t know, but as the whole point is anonymous and they have no proof who you are…).
It’s great that he’s willing to go. I imagine, I hope you don’t mind me mentioning, that you may be wondering is this really what he thinks or is he doing it to placate you : try to focus that it’s really hard to take the first step, even a tiny seed of doubt planted in his mind is great.
This is the part where, I really hope for you, that you can hope the professionals will take over. AA isn’t therapy, he won’t need likely 10 sessions. They will be very accepting and non judgmental hopefully, and a huge factor is being around absence of stigma and people who have succeeded.
Be prepared that he may freak out and run ; you can only hope the group will handle it well, he wouldn’t be the first. Ex suggest coming back in a little while, this part is just guessing though, I don’t know the inside. You’ll at least get some sort of estimate idea of the timeline.
I would definitely focus on today : on praise and how happy you are and proud. That you know it’s a medical condition that’s not his fault, that you know he wants to be a could dad (maybe avoid the word husband, don’t make false promises.
So, for now, yes, all positive attitude, if possible big hugs from the kids before going, just focus on getting him to that first meeting.
Afterwards there’s less you can do. You can only hope. Ideal scenario is he gets into rehab and it’s all managed there by the professionals, you won’t have to decide much, they’ll advise you. As would happen with any medical condition.
There’s never any guarantees, but this is a good step towards at least trying (don’t phrase it like that to him). I would think a call to AA to ask for their advice would be worth it : tell them exactly what he told you this morning.
Then just take it from there.
Best wishes, hang in there for today, and try not to think about tomorrow or even further, life can go so many ways, all you can do is give it a chance. Re getting your hopes up or not, it’s the same re anything you try to achieve in life, it’s just trying your best (you have, and now you can only hope professionals will step in), and hope for the best.
