<human>: Condense the text into a few key points

Let me start off by saying that my (ex) girlfriend is amazing and I feel no animosity towards her. That's probably what made the break up so hard. We have not gotten in a single argument worth mentioning. I leave for college next week and she is a senior in high school.

Early in the Summer we had known that this probably would happen and that we needed to talk about it. So we did and we put it off until last night. We mutually broke up so that neither of us would be angry with each other which made the last hour that I had with her extremely hard, because the thing is I found her perfect and we were compatible with each other, but we felt that it would be best to call it off. 

After we said our awkward, tearful goodbyes I got into my car and started sobbing. She told me this morning that when she entered her house she did the same thing as she watched me pull away. And here's my question: If this is meant to be, if it's truly best to break up, then why does it hurt so bad? Why are both of us sobbing and miserable? Why did neither of us sleep last night and why do we miss each other more than anything in the world? I don't know what to do and I just feel empty. I've felt a pit in my stomach and I feel extremely nauseous. This amazing girl was my first girl friend and I was her first boyfriend which probably adds to the sentiment. I feel lost and I probably mostly need someone to talk to. I would appreciate a response from anybody. Thanks for the long read.
<bot>: I'm heading off to college, my first girlfriend is still in high school. We broke up last night under the stars in good terms but I'm miserable and don't know what to do.
