My boyfriend is an alcoholic...

   Some of you may be familiar with some of my posts. I've been in an on/off again relationship for six years & have been trying to conceive off/on for the past year. At the moment, I've decided, I'm not ready to bring a child into our lives until we decide whether or not we're going to stay together & make this work. 

My boyfriend has always been a drinker. When we met, I was in my early twenties, and he was a few years older. The drinking didn't bother me then because I indulged in the drinking & partying life style as well. Now that I'm older, I don't party at all & im only a social drinker. The past few months my man's drinking has increased. He even blacks out now. One night a few months back, we were having shower sex & he dropped me. He was so drunk that he blacked out & didn't remember  the next day. I spent the next day at Urgent Care because I thought he had fractured my shoulder when he dropped me!!!! 

At this point, I'm worried. His family is also. He goes through three or four bottles of Vodka Grey Goose in a day. I want to help him but he's in denial. I'm also thinking his drinking is causing him to not be able to conceive...What do I do? I'm so so worried about him.
