That can be a very unhealthy attitude to have, for both of your sakes.
If any part of what I said is right, my advice is that you seek a therapist to help you through your feelings. It sounds like you'll struggle to work this out on your own in a healthy way. And also, talk to her. And keep in contact with her when she moves away. Hell, if emails and phone calls seem too impersonal, Skype (or similar) is an excellent way to communicate long distance.
