I told this guy i liked him, and i think it ruined everything??!?

well maybe not a problem, but idk. im not sure what to do. i liked this guy and i told him i liked him, but we dont go to school together so i only talk to him on internet or phone, but i see him on sundays bc he is in my youth group. well i told him i liked him 6 days ago or so. and then he like quit talking to me and i was so confused and didnt understand. so i figured he didnt like me so i just sent him a message saying i regreted telling him bc i didnt want to ruin our friendship and all kinds of things like that. well yesterday i found out that he has been grounded so there was no way of him responding to that. then this morning i went to church and i wasnt sure if he knew i liked him or not. i think so but i didnt ask. well we were talking and that was fine. and then this girl came around and iver never seen her. but im uming by the way they acted they are dating. now idk what to do. bc i told him i liked him, then got a bit upset at him bc he wouldnt talk to me, then told him we should just be friends and now he is dating some other girl and i have no idea what to think. or if i should be mad or upset or omgg im, im just not suree. helpp. pleasee. =]
