Here's what I posted on a similar thread - your circs are a bit different but I still think the advice holds good ...
I am a (male) recovering alcoholic myself.
PLEASE get away from this man, and stay away, until he:
- accepts he has a problem AND
- stops drinking AND
- seeks ongoing help with living his life drink-free.
Apologies, pledges, good intentions are all great - but until he ticks all three boxes, keep him at arm's length, for everyone's sake.
For me, (3) was AA and I have yet to find anything else which I imagine working for me, but all power to him if he does - the point being, though, that whatever he chooses, stopping drinking is the beginning, not the end. All the problems he drinks to "deal with" will still be there, unanaesthetised, when he stops.
On the plus side, I can confirm that my life is now fantastic as a non-drinker and, although not drinking is not something I am complacent about, it is NOT, as someone cautions above, a "challenge." My life is SO much easier and more pleasant these days!
That said, I'm not at all anti-him, in fact I both empathise and sympathise. Please let him know that he is welcome to contact me if he would like to hear more of my story.
