<human>: It hurts every time I think about it. Any other relationship I would just let it go. But it's so hard after all the time that was put in. The moving in, doing damn near everything together, etc. We were doing well for so long. Then all of a sudden it just fell apart little by little. In the back of my head I want to fight for her again like I have done a dozen times. But then I wanna say screw it and let it go and just stay friends. 

She feels strongly like we can't be fixed. But I think we can if she were to actually try. We were both at fault many times, and most of those times it would be a one way blames towards me when she would do the same things. I would always apologize and try to fix my mistakes. She rarely apologized. Anytime I would try to talk to her normally, she would think I'm calling her the bad guy and "turn it back on her". I try to explain there is no bad guy and that it takes two people to work on a relationship. Attitudes would get thrown towards eachother, arguments about small things, she would be upset when I chose not to do things for her (when I pampered her damn near all the time). Overall in the end of us she said that she blamed me half of the time to take attention off of her and her self problems. The problems that she is supposed to talk to me about.

Can you give me a shortened version of the text?
<bot>: Need to know if I should fight again for her and attempt to fix it or learn how to move on and do what's best for me.
