Help!Does he like me or not?

oKAY... this guy has always looked good to me... so i was walking to a room with a reall heavy door so he sees me runs to the door and opens it wide for me, then he exteds his hand and smiles big, then he runs to is friend again. He always looks at me, not staring but mesmeroizing... Also one time when i was walkin to the school office he was with his friends walking into he clroom, he looks at me not noticing me at first, then turns his head immediatley too look at me! does he like me or not... He always smiles at me and does actions to show kindness, hen we have never spoken before! AND HES SO CUTE! :D
