I believe that in one way, he is an alcoholic or at least drinks a lot, because his girlfriend is very cold to him and is never completely satisfied with his part in the relationship. He just wants to please her, he doesn't want to leave her, so he turns to alcohol.
Or it could be the other way around, that she is so cold to him because he drinks too much, and her harshness when he comes home is something that sobers him up.
