<human>: Provide a brief overview of the text.

Background: We've been together for almost 5 years, and have been living together for a year. We moved to a new city when we started to live together - we both wanted a new start after losing our jobs in a short span of time back home.

The relationship is at an obvious end though. I find myself not caring about what she has to say anymore, I don't care about her problems, and I don't really care about her feelings. That's obviously a glaring problem. She doesn't deserve that, and it makes me feel like a shitty human being (well, because I'm being one). Our relationship has no future; we both want different things - one of which is kids (she wants them, I don't).

She, however, through all of my bullshit still loves me, and still has a desire to marry me (we aren't engaged though). 

I need to end it so that I can move on and find someone that I can treat properly, and so that she can find someone that deserves her. But I can't. I'm a 26 year old man-child, who can't find the courage to do it.

It's not my first breakup, and I'm not even afraid of being alone. But as soon as I think about how much it will hurt her, and how awful it's going to be living with her after I end it (until she moves home, or I move away), I lose the will to do it.

I'm not sure anyone can say anything beyond "It's obvious you need to end it, sack up and just do it", but I'm hoping someone can help. I feel like a coward who can't find the courage to do what's right no matter how logical it is.
<bot>: I need to find the courage to end a relationship that's very unhealthy, but I'm a coward, and scared of how it will hurt her and of the time living with her while we are broken up.
