I'm having a little trouble too, but I think I get the jist of it.
If distance has only increased your love, then wonderful. I say marry her, as long as she feels the same way still. Plus two years is a good length of time to wait. That way you will be positive you are in love and that you will last.
My bf and I are doing the same. We've been together for a year and a half, but we will marry in two years. Unfortunately, I'm still waiting for my ring. I hope he gets me one some day soon.
