How to attract a good guy, who is kind, quite and a bit shy?

so i just had grad. and through out the dance a guy, will (an old Friend of my ex) started to hang out with ,y group, since most of his Friends either chickened out, or left early. i had fun dancing with him (though we had 2 teach him how 2 fist pump) and he seemed to have fun to. we slow danced together for the last song. it kind of changed the way i saw him. we also got each other photographed in the yearbook. the next day at school we talked but not for very long. when we got home we chatted up a fire on facebook and all weekend. we are going to hang next weekend. i have never felt this way about a shy guy. ever. i have no idea how to dress or act around him. what to do or what not to do.... HELP!! I THINK I LOVE HIM
