Right Wtf should i do?

Ok here goes. I'm not normally like this but this is not going away. There is this boy I like. *I can hear the groans from everyone as they read it* Anyway I started liking him when he got moved and started to sit next to me in English , we have English a lot , so I talk to him quite a bit. Now I really fancy him , like properly, every time I think of him I get erfly's in my stomach and i have dreams about and this is seriously scaring me. I don't normally get infatuated with boys often , there have only been a couple but i have never felt like this. We really do get on and have a lot of things in common and he is awfully smart, I haven't told anyone else this because I find it embarring and he's not considered as fanciable as others. So how should I found out if he is interested in me and how could i grab his attention a bit more?
