How Pisces men react if they know you like him?

Well i know a Pisces boy in school that told me he liked me since 2011 in class (i'm a Capricorn teen by the way), he came to my school because he was expelled from the last one. after me and him wasn't in the same class anymore (2012) i told my friend to tell him that i like him. he started to stare at me often in recess and telling people i like him secretly but i knew. he now goes home the same path i go home just to see me in my gallery washing clothes sometimes -_-, he stands on a block and literally looks over. In school tries to make me jealous with girls from his class and it doesn't work because he looks at me while trying to. He thinks he has it all. And later on he puts his shoulder over me and tells me he misses when we use to be in the same class. But these days I started to feel he doesn't like me anymore so I lost a lot of weight and in sports boys give me attention and I pretend he isn't there to hurt his feelings i guess. I add him on facebook he accepted me and i told him hi he never answered. since December 2011 he's currently in a relationship.. (Yet he does all of that for my attention). Hope my story answered the question..
