Hi, the way you describe your relationship, i dont see why being separated would negatively affect your love and wanting to be with eachother. I sense your a bit insecure in her being away from you.
I have tried and failed at a couple of long distant relationships in college. It may work to begin with but chances are with the distance it is going to be tough. Not saying it can not work or will not work but it is tough. You will have friends and she will have friends and you will be doing different things at different times. And the last thing either wants to do is cheat.
So I think this is something where you and her should sit down and have a nice long talk about.
We've had the conversation and she just "doesn't know" but she says she wants too. My biggest issue is thinking of us breaking up that we will drift apart over time and not see each other
If You are 'committed' to one another, well then, 'distance' won't change that.
One doesn't stray from a commitment because there is distance. If one strays it will be because one is not as committed as they believe themself(ves) to be right now.
