AITA for asking my Husband to quit drinking ?

I (28F) have been with my husband(29M) for the last 5 years. When we started dating I knew he used to casually drink in the weekends or for special occasions. I drink maybe two cocktails for special occasions. But since the last two years, he’s been drinking too much. And when I mean too much, it’s like he gets a 750 ml of whiskey and drinks it all by himself in two days. He drinks every weekend, and any weekday he claims to be stressed. Now I do understand that he has a stressful job, which is very demanding. I try my best to do the household chores and cooking and cleaning so that he doesn’t have to. I also do a full time job, but it’s not as demanding as his. We don’t fight over any other topics. We don’t have any financial stressors or other family problems.

We discussed multiple times over the last year that he needs to find a way to deal with job stress, instead of having alcohol as his go to solution. But the problem has only become worse. I tried talking to him about the ways I can help him, but he says that me asking him to quit only stresses him more, and makes him want to drink more. He’s been saying this for the last whole year. I have tried giving him space so that he’ll figure it out on his own, but that hasn’t helped. He has promised multiple times that he’ll keep the drinking minimal and to two days a week, but hasn’t kept his word. From thanksgiving break, he said if I leave him alone in the holidays about his drinking, he’ll start the new year by completely quitting. During this time, he drank everyday straight, entire December. But when new year came, that promised only lasted two days. A week ago he again said that he’ll try not drinking for the next ten days, but drank two days later. I’m worried that he’s getting into an addiction problem. If I so much as bring the topic about drinking alcohol, he claims I’m making it worse.

Today we had a heated argument about this, I requested him to not drink one week to get started. He said I am nagging him too much and that I am stressing him out and went out to get some more alcohol. I don’t know what to do. I feel like an asshole for asking him to quit . What should I do… I feel like crying but I’m also very angry ..
