Girls n guyz i wanna know what u feel about this?

i hav recently started talking to a girl on a social networking site n we have become good frenz, she even asked 4 my no. n i gave it to her but we have never talked on phone,just exchanged a couple of smses but now i cant get her out of my mind.I think of her all the time though its odd as we havent even met and at present we r not more than friends.I am apprehensive whether she shares the same feelings.I dont even know whether I love her or its infatuation.Should i disclose my feelings to her or should i wait?I know it would sound really stupid n made up if i tell her that i love her as we have never even talked as in on phone or face 2 face but then i cant get her out of my mind.Please help people,its really taking a toll on my day 2 day activities n my studies n i cannot concentrate on anything n also pls ans as to how can i get myself not to think about her all d time.Is confessing to her the remedy?
