Call her up, and tell her how you feel. It'll be hard, even if she doesn't pick up the phone. But you must tell her someway, even if it's e-mail. You need to have these things off your chest even if they don't work out you need to know at least you tried. She might even compromise and become friends again. If nothing else works, just say, "I'm always ready to be your friend, even if it takes you years, I'll be here waiting with open arms."
