What should I do in this situation?

I like this guy but I don't know how I'm going to ask him.boys at my school dont ask girls out. 10 points goes to the most detailed less critizing answer. I'll give you details so you'll understand I'm 13 ,I know him we are friends, he smiles at me, sits next to me in class, tAlks to, nice to me.my question is does he like me and should I ask him. Yes I know it's my choice but I want a second opinion . Arty bout mistakes I'm typing on a phone and it's sorta hard
