the boy of my dreams doesn't talk to me and i love him dearly

i like this boy and i told him an he have been actin very strange.He does talk back to me when i speak and though i know that he has feelings for me he will never tell anyone. Because he is always looking at me .Once he came and stood right behind me and kept staring at me.I really love him alot and would cry if anything happens to him but sometimes i think he doesn't deserve my tears but today he was waiting on me when i came to school but he never talked to me i think he loves me to but is just too frightened to tell anyone cause rumors spread like fire in waterloo secondary.What should i do to make him open up to me?
