Inlove or infatuated?

well, i really like this one guy. but we havent really had a real conversation. my friends say i cant be liking/inlove with someone i dont even talk too. at all! &that im just really infatuated. but i really really like him. like, my day is incomplete without seeing him. knowing he's at school makes it easier for me to get through the day. &everytime i see him, i get this really weird feeling that i basically forget what im doing. and everytime he pes i try to act serious but i always end up smiling... hmmm. oh yea, &i cant stop thinking about him. even at random times he just pops up in my head. o.o
