Alcoholism - grounds for divorce?

My husband and I have been together for 6 years, married for 2. He has been drinking since the day I met him, I thought it was just a phase and he would stop. Over the years it has only gotten worse, it is now 8-10 beers a night sometimes more from the moment he wakes up till he goes to bed. He understands that he has a problem but not willing to give it up just yet. I’ve always been concerned and turned off by it but now it completely disgusts me. He doesn’t get angry drunk I just don’t think that I want to live like this anymore. I think his anxiety triggers the need to drink to calm down, but I just can’t anymore. I’ve tried to be supportive, but this prevents him from getting a better job, us getting pregnant, moving on with our lives. I feel bad giving up on him, I just think these things are slowly killing all the feelings I have left for him. I don’t want to have sex or cuddle or kiss or spend time together, but miss him when we are apart. What to do? Help!
