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

Been with her for a few years now and have known for a while that I'm not gonna marry her. I am more happy when I am alone or with friends than I am while with her.
I have tried to end things a couple of times but end up backing out. I just can't do it in person. Emotions run high and it just really complicates things. I know it's best for both of us, but I just can't make it happen, and I know she wants to stay.
As bad as this sounds, is there an easy way out? I'd hate to do it not in person, but if that's what I have to do, I'll do it. I'm just very very weak wen it comes to breaking up.
