Does my crush like me? 10 points for Best Answer?

[Erin]

Ive liked this guy for a few weeks, were not in any of the same classes this year, but last year he was in my homeroom. He's really cute and nice, but we never really talk anymore. Anyways i notice every time i pass him, see him at lunch or in the hall he always stares at me, likes he checking me out. I also noticed when i looked at him, he was talking to his friend and they were both staring at me, like they were talking about me. Another time he was standing in front of me in the lunch line with friends, and one of his friends was saying heyyy (my crush's name) look who it is and pointing behind, where i was standing, i noticed my crush blushing a bit and telling his friend to shut up, and then he looked at me quickly and looked away when i noticed. So does it sound like my crush likes me? Also,i messaged him on Facebook but he never answered back. I know that he is pretty shy but Does it mean he doesn't like me? I know he doesn't go on Facebook much so im not sure. I want to get to know him better, but i don't know when to talk to him, i don't have his cell number. A few of my friends are in some if his classes, could they maybe talk to him for me? Or How can i talk to him more often? Please help! Thanks
