Please forgive the comment, but Alcoholism is not a disease. It's a
choice.
So whilst I can understand your dilemma - I'd be furious.
Letting alcohol pass his lips when he was supposed to be on the wagon, is something he decided to do....
This breaches your trust.
I know this was a huge bone of contention between you both, some time ago (I looked at your past threads) so I know how hard this must be for you.
If it's a minor lapse, that's one thing.
But if he is not going to make the effort.....
I don't know what I could add, other than for me, it would be a deal-breaker.....
I really wish you all the best in the world.
But I don't envy your position....
