can anyone help with this problem a guy problem?

so i like this guy, a totally diferent guy.hes in my class and i didnt really notice or know him for a long time.i really like him.when i liked other guys i always took a long time to like them.like i had to get to know them and stuff.but this guy,well call him edward,i liked instantly. well not instantly but the first week and i fell for him.and i really really really really like him but i cant do anything.at first i only told one of my friends but then they told him that i liked him.and before they told him i liked him he'd talk to me. and now he knows that i like him and he doesnt talk to me or even look at me.i try to act like that doesnt mattter and i dont care but i do.and then a few weeks ago he put his arm around me and then a few days ago he started touching my books and stuuf and then tiday he said that i try way too hard. and that made me think-does it look like i actually try to get his attention.but i dont i dont because i try not to get his attention because i get reallly insecure.anyway this is my last year in this school and stuff and hes a guy i really like and i dont know what to do.my brain is telling me to be independent and stop liking me that hes stupid not to notice me and thats whet my friends tell me too.but i just cant stop the attractioni feel towards me.

any advice anyone????
