My DH is a high-functioning addict. He drinks every single day. 2 bottles of wine a night or 10-12 cans of lager, sometimes whiskey and/or gin on top of that, other times just a bottle of whiskey. He can hold his drink very well, and if someone didn't know him, they wouldn't have a clue.
I don't drink at all, not even on special occasions/birthdays etc. His alcohol use has always been a problem for me, although when we met at University over 30 years ago, I would match him drink for drink, but that changed as I matured. He often reminds me that I used to enjoy alcohol too.
Last night we argued because he told me he had come to an end of doing dry January. His dry January was zero % alcohol lager every day, with whiskey on top. To me, there is nothing dry about his January, but I got severely criticised for not being supportive of his attempts and for always looking for the worst when I pointed out that whiskey isn't zero % alcohol. He felt I should be celebrating his choice to drink alcohol-free larger and should be supportive of his attempts to drink less.
But besides that, I found evidence of him using powdered drugs a few weeks ago. I've always known he has a tendency towards substances, but I thought that was over, considering we have teenage children and he runs a successful company which comes with many responsibilities. When I confronted him with the paper wrap I'd found, which had remnants of white powder, he told me a long story about how I should be congratulating him for being an occasional user and that he had a serious problem a few years back, which he concealed from me, so he had done very well to cut down his use. I always had my suspicions, but before, I never had the evidence, and if I asked him, he denied it. I feel betrayed and like I'm in a bind. Despite him being the one creating problems in the relationship, he turns it around to make out I'm the problem! AIBU in not 'celebrating' with him???!!
