The guy I like gets teased at school because he likes me back?

This exact thing happened to me except we didnt like each other we were just super close friends, but he could never admit to any of his friends that we were best friends because they would tease him. Talk to him about it and tell him how you feel and tell him that if his friends dont want to except it then he can ditch them and if he wont ditch them then he never liked you enough anyway
