Well you should talk to him but dont look like you like him,try to make him go after you.
Boys are like that,the more you go after and show at once your fellings the fast they go away,so you have to do the oposite of that.
Try to flirt with him by looking at him and then ignore him that way u will let him consused and he mithg end up going talking with you :)
go for it girl ;)
