<human>: Can you condense the text into three sentences or less?

So my girlfriend and I have been hooking up for a long time, maybe 2 or 3 years, but we just made our relationship official in March, which means we've only done the long-distance thing for about a month. This summer has been awesome with her, we both have similar interests and we enjoy hanging out with each other. Since both of us are living at home we've met each others families, and everyone gets along great.

She goes back to school on the east coast this Friday, and I go back to the midwest in two weeks. I just don't think I can do a long-distance relationship for an entire school year. We *might* be able to see each other once a month, but even that would be a struggle. And I don't have a weekend to give up every month.

My problem is: how do I convey this to her? I've been thinking about this for weeks-- I literally haven't cried so much in 20 years of living. The problem is that the relationship is awesome and I don't want it to end, but I think it has to. She's like my best friend, and it's like cutting out a huge part of my life.
<bot>: GF and I go to different universities. We have a fantastic relationship, but I don't think it can work long distance.
