About guys ( of course)?

ok well there is this guy i like and we have every cl together, and my best friend has all cles with me too. and im really great friends with me. so anyways my friend katie started being like a physco ***** but then we were all nice to each other and we got icecream and she asked me who i like so i told her. her and jesse are friends to but she has a bf already. so anyways she started acting all bitchy again so i got all mad at her. then my crush started acting all weird like y r u staring at me and give me weird looks and scooting his desk away from me and its not in a joking way anymore now he is dead serious. so i think caitilyn told him. what should i say to caitilyn and my crush?
