<human>: Could you distill the essence of the text into 1-3 sentences?

Hey guys, never been here before, but I think I want to break up with my girlfriend. Here's a recent history:

We were good until this summer began, and things have been off ever since, with more useless arguments that led to me saying we should break up. Because I had been with her for so long, I decided to keep trying. Couple weeks pass, the hang outs are okay but something is definitely up. 

This past week I hadn't really seen her because all my friends moved in so I spent the weekend with them, and she was being mean about it, but I knew it didn't really bug me that I didn't see her for so long. 

Now we're meeting tonight to talk and everything seems shitty, but I still have this feeling of doubt. I do really care about her, but I don't know if I want the relationship. Its been like this for two months. She said some things last night that hit hard.
<bot>: I'm torn on whether I should end a 2 year relationship when the past two months have been hard. Help please!
