What should I do with this girl that has a crush on me?

well, there's the girl i never talked to in the college who had a major crush on me. Later I began to like her too. I once tried to talk with her but she blushed, avoided eye contact, turned around and refused to answer any of my ques like what her name is(i never talked to her so i guess that's the way to start a conversation)... Of course she ran away from there after i showed my disapppointment and told me to learn the answers from other classmates while running :). some girls suggested that she was probably playing hard to get... However from that day all the chicks in my college began to act strange in front of me. So I stopped talking with every girl(like a gay). They probably think i am her guy. Well, we still have eye contact everyday but I don't like the concept of hard to get. So I am not making any move.....

Help me decide, should I talk with her again or move on(won't be tough since I dont know her very well). One big problem is she is the hottest chick in my clg, honestly.

P. S. I never smiled at her during any eye contact and never gave a return smile
