So your only in it a year or so?
You are in for one long and miserable life if you stay with him while he's an active alcoholic.
Did you see that Oprah where she said "always believe a person when they tell you who they are"...
Well he TOLD you who he was. A raging alcoholic and you didn't believe him. Now you do.
Unfortunately your emotionally invested and here you are.
I would suggest you read thru this forum. See what those of us have gone through with our spouses/bf/gf 's before you decide you want to hang around for the long haul with this guy. I wish I could tell you he's really going to quit and change his life but I can't and I personally think you need to get away from this situation as fast as you can...but also go to alnon as someone suggested to find out that even though he told you what he was you still found that acceptable (not calling you out; I'm saving you a seat! BTDT)
If I had known then everything my husband would put me through over the years I would have left him before I got in so deep.
