hmmm... who knows man- the bottom line is that she IS leaving for college and doesn't want to be tied down.

If you want to leave the door open and just be friends, by all means do so... be someone she can talk to, and maybe in the future you guys will end up together, maybe not.

But at the same time you have to realize that over the next year she is going to change very dramatically, and you might not even want to be with her after that.
