<human>: Can you give me the gist of the text in a nutshell?

I (27f) have been dating my boyfriend (27m) for 3 years. We live together and despite myself I started fantasizing about the potential for our relationship a long time ago. I tend to get caught up in my relationships. 

Here is the good: he is affectionate, funny, smart. When we play it's really great, he doesn't get worked up about little things. The bad it's that he is depressed, which makes him less fun to be around.  He has lost a lot of motivation and is dwindling in some of the qualities that attracted me to him. 

The biggest issue is that I can't ever bring up something that bothers me without it starting a fight. I brought up that he was drinking more than I wish he was. Fight. 

I'm struggling now because it's hard to plan a future v(Even tentatively) with someone when there are glaring communication issues that he says he won't work on. 

I hear myself say that and know it means break up, but those issues only come up every once in a while and our day to day is good. So I waffle between happy with hope we will get through it and sobbing because I know it's ending. I can't just move out because I can't afford to and I'm mostly all he had for friends right now. It kills me to think of him alone and sad.
<bot>: I'm Obsessing over whether or not to end a relationship where the everyday is good, but we have long term issues.
