Are we more than friends?!?!?!?!?

okay, so i have this best friend. and we are very close i just moved so we just met but we act like we've known each-other for a long time! well he says stuff like "your boyfriend is lucky to have you" and your amazing and always flirts with me and today he sang the chorus of just the way you are by Bruno mars! i do like him...but by the sound of it..do you think he likes me?
