You'd be giving up three years of meeting other people in order to try to make things work with her. Then because you've only gotten to see her once a year, odds are likely as not you'd discover some way you were incompatible once you were living closer to her. It's a huge sacrifice to be making for something that's likely not to pan out. If you're a traditional college age student, then you're still young and will have plenty of opportunities to meet other girls. I think you're better off ending things with her.
“This planet has - or rather had - a problem, which was this: most of the people living on it were unhappy for pretty much of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movement of small green pieces of paper, which was odd because on the whole it wasn't the small green pieces of paper that were unhappy.” ― Douglas Adams, The Hitchhiker's Guide to the Galaxy
