why does he confuse me?

[Sarah]

Hey! Ive liked this guy for 2 years now,however last year it just seemed like i always made the effort and he would never even notice me. Everyone knows i like him as well as his friends. His friends once asked him why doesnt he just make a move (because hes really quiet) but he just smiled and didnt say anything. I always useto try and talk to him face to face and on facebook,twitter yet he was very short so i gave up in the end yet still do like him. However,now that whenever i see him,i dont look at him and just pretend hes not there,but when i walk past him,he looks back at me and so do i so its kind of awkward,we just look at eachother. One day i was talking to this guy and i turned around and i seen him staring and quickly looking away. I dont understand.Im really confused? Sometimes we would just stare at eachother for long but thats it. Im really confused? Is he trying to play with my head? What do i do? Hes really quiet? So i dont even know how to talk to him now.. Help?
