That's a toughie, and you're going to have to do some thinking. Whatever you decide, don't do the halfsies thing, where you still are sorta together, but sorta seeing other people. You two will just end up hurting each other.
If you're head over heels crazy about her, and you want her in your life for a long time, try to stay in touch, but watch your phone bill!
If you're too uncertain, call things off for now. You know what they say, "if you love somebody, set them free." And if they come back to you, then it was meant to be. If they don't, then you were meant to move on to someone new!
You two are still young, and people change quite a bit at that age, especially when someone travels somewhere distant.
Good luck!
