This boy who I like and find attractive has been caught checking me out (a lot). he's starting to seem to lose interest, looking at me less and stuff and looking at the ground or never at my face when I pass him. I was gonna smile at him or say hi but he doesn't look at my face anymore! I've heard its because of intimidation..Firstly, should I introduce myself? What'd I say! I'm very shy and how could I say this?
