What do YOU think?

Pe
     Hi I really need your opinion. Pls answer, 
    So there's a guy I like.. And Everytime I see him he puts a lot of space between us when we walk past each other in the hall. He walks in the class and says hey to everyone but me. He moves whenever he sees me around in close proximities to him. He'll glance at me then move away from me. 
    I don't know if he knows I like him or not but I don't like what he's doing. It's reminding me of past experiences when guys knew I liked them.
