Does he like me? Getting mixed signals...?

[Nicole]

So I have known this guy for 3 years now, but only recently started talking/Messaging eachother. I really like him, especially his personality, and wanted to know if he liked me. This is what he does:
~ Sometimes shows up where I am on the School Campus
~ Stares at me in class, but when I look he looks away after a second
~ Lingers near me in art class
~ Seems a little nervous around me
~ Watches me from a distance, like when i walk home and hes waiting for someone to pick him up.
~ When Facebook chatting he asked me questions like what my favorite color was, etc. and gave me compliments.
I'm getting some wierd signals, like he just logged out of chat without saying goodbye or anything. I was walking by him, he was sitting against the fence waiting for his mom, and I said hello and he looked up from his phone and said hi but looked down really quickly, so I kept walking. After about 20 ft, I looked back and he was watching me. I'm really confused, please help! He dosen't have a standard group of friends he hangs out with, and we haven't really talked about stuff other than school. He's never started any Facebook Chats. I'm a pretty shy girl so I don't want to ask him out unless I know he likes me...

No hes obviously using you! Can't you see it

I would just ask him out, it seems like he likes you, but in a stalkerish way

[Bored Dude]

i think he likes you just is super shy so tries to hide his feelings from you so he doesnt get rejected if that makes sense?

Sounds to me like he is also shy. Two shy people hanging out together is awkward. I know, because my wife and I are both really shy, and now we have awkward children.
