What should I do about this 'girl problem'?

So there is this girl that I'm friends with in University, and I've been interested in her since I first met her. She is Intelligent, personable, and unbelievably (no exaggeration) beautiful. We're in the same faculty, similar interests, and we get along well. But the problem is, is that she already has a boyfriend. Her boyfriend goes to a different university...and she has never brought him up in conversation.

So my question is: What should I do? Should I just wait and see if she becomes available? I know there's not really anything else I can do but it kills me to see her everyday and to have such strong feelings for her yet not be able to do anything about them.

I really like this girl. She is perfect in every respect of the word. I have the feeling that no one else could possibly compare to her.

Thanks for reading, and I'll appreciate any advice you can give.
