I like this guy iv seen him looking at me but lately hes looked away when iv ped him does he fancy me?

i see him every day at school which normally wouldnt happen because hes in sixth form and whenever i walk ped him he sometimes looks at me and we have made eye contact before. my mate has told me that she has seen him looking at me before and she thinks that he likes me because she says he cant take his eyes of me but i dont know if shes just saying that because shes my friend. he has smiled at me a few times and he has gone red when ive been near him, hes a few years older than me. lately whenever he has walked past me he has looked the other way like he was avoiding my eyes my mate ses its because hes shy but we dont actually know if he is, ive never really spoken to him before. do you think he fancys me and how can i get him to speak to me when i only p him in the corridor or playground.
