<human>: Give me a shortened version of the text

So, throwaway account for starters since she knows my reddit. 

I am a pretty mild guy who really doesn't like confrontation. She is an easily slighted girl who never forgets grievances and argues constantly with her mother forever. Since we got together anytime she has had an issue with something I've done or not done, she thinks we need to hash it out. If she said I did something, I would agree, apologize and try to learn from it. This would piss her off because she wanted me to argue back, say what was on my mind, etc. Well we have been constantly fighting since January and I always argue back, defend myself, explain why I did what I did. Now she wants me to stop arguing, take responsibility when she lays a claim against me, and apologize. So I have tried that, but now she says my tone and facial expressions are wrong. 

She says she is done fighting, she says if any of her friends told her they were in this situation then she would tell them to get out, but she won't break up. I don't want to break up because I do love her, and I don't want to throw away 8 years because of a 6 month rough patch. Plus I feel guilty because we are both in school, she has pretty hefty student loans (I have none) and years ago I asked her to move with me when I got my first masters that didn't go anywhere. 

I know I have made some pretty bad mistakes, I haven't been mindful enough a lot of the time. I am really single minded and if I know I have to get something done I will often shun her, which has led to a bunch of sexual frustration and issues for her because I will turn down sex if I have a paper to write or work to do etc. 

I think I wrote this to be more cathartic than anything. But any thoughts would be appreciated.
<bot>: girlfriend and I have been fighting constantly since January. I don't want to break up with her while she claims that we need to break up yet has done nothing about it.
