<human>: 24/m & 21/f together 7.5 months. Not living together.

So my boyfriend likes to drink. A lot. When I met him it initially didn't bother me. He had this magnetic personality that drew me to him and he was a lot of fun. We could talk all night, drink beer and watch a movie. It was almost perfect. There have been moments through the past year that have made me question our lifestyle though - moments where we've gotten in fights because he's so drunk he took my concern for his well being to mean something condescending and passive aggressive. I very rarely have a "fun night out" anymore, it always devolves into me driving us home or taking care of him in some way.

I've given him some bit of leeway - that this behavior might be because he's simply bored/coping. He's working a service job and sort of biding his time until I graduate (he's been out of school for a year or so) and he's also legitimately lost two people he knew for his whole life in the past year. 

He's never been outwardly abusive - no hitting, no real emotional abuse other than what (I see) has been accidently misconstrued while being drunk. But lately I've found myself missing the person I fell in love with. I like the man that makes me dinner, takes me on hikes, watches and makes fun of bad movies with me. The drinking is getting worse - we are having less sex and I don't feel loved. It's sad I'm starting to live for the brief 20 mintues in the morning where we cuddle and I feel loved and safe again. 

We are fairly open with communication but I just needed a little validation before I bring this up. This is a big issue and I don't want to cross the line. I don't want to break up with him. Is this alcoholism?   My point of view is that if we are going to be in a serious relationship, a lifestyle choice has to be made or else he's probably going to lose me when I can't handle it anymore. 

Sorry, relationships, at this point now I'm just talking to myself.

Can you summarize the given text in a few sentences?
<bot>: Pretty sure BF has drinking problem, trying to figure out if it's out of line to bring it up and try and work with him to better his life or to just give up and leave.
