Love and Separation

I am so much love with this girl, and she loves me dearly. But in about three months, I have to leave my country forever, and I don't know how I can keep in touch with her as she is so very busy. Normally, we meet everyday or talk on the phone. We say "I love you" everyday. How am I supposed to do that when I leave her? I want to marry her, and she wants to do the same with me. I am afraid that she will break contact with me or something else. It is not that I don't trust her, but I can't figure out what to do. Maybe I wasted your time, but it is painful to me.
