I like this guy but I'm not sure if he likes me back what do I do?
You could have one of your friends ask him or have your friend ask one of his close friends, Hope this helped :)
ask him out
Either ask him if he likes you or ask someone else to ask him for you.
Ask him. Don't have your friends do it either; that's a little childish.
Get his best guy friend to ask him
You should get a friend or a sister or brother to say that you wanna know if he likes you
