<human>: Give me the gist of the text in a nutshell

Reddit, my girlfriend of 4 and a half years is driving me insane. We got together at the beginning of college, and now we're living together, working in the real world. We went to a really hard school, so it was really difficult sometimes. She would constantly be stressed, and that was frustrating for me, since I didn't take it so badly. She was definitely having a harder time than most, probably because she couldn't take failure, which to her was getting anything below an A.

Anyway, I figured once we graduated it'd be better. I stuck with the relationship because I love her. But now, it's worse. She wakes me up in the middle of the night, throwing up from stress and worrying about work. She complains that I don't spend enough time with her, and is very very needy. She gets mad at me for not doing enough around the house.

For the record, I give the apartment a fairly thorough cleaning every weekend or two. I commute into work, 2 hours each way, so I'm only home for about 3 hours before bed during the week. I always need a few hours to myself each day, so it's hard to spend much time with her in her way. To me, when we're both on the couch on our separate laptops, that's spending time together. To her, that is my alone time.

There's dozens of other things I could complain about, and I think about breaking up often. But I can't believe that that would really be the solution. When we met I was sure I would marry this girl. Are we really just not compatible?
