I asked my crush if he had a crush on me and he said, "I don't want to tell you that yet". Do you know what this means?

Why don't you ask him, instead of asking some 2 bit backwater website and its less than capable users?

nope not at all.

i have a crush and never even told him i like him yet. i am to scared to tell him

Maybe he might like you or maybe someone else I'm sorry I'm not very good with pag-ibig stuff but I can try to help you. Do you talk to him a lot because if you do he might like you, maybe he's too shy to say it if you don't talk to him a lot he might still like you.

I used to have a crush on this girl at school, but Truckmstr1997 told her I play with Pokémon, thus giving her a reason why she doesn't like me. (Before I even told her.)

Maybe he likes you but doesn't want to rush into it... Just give him a little time.

it means "have fun in the friend zone lol"

U, it means that he doesn't want to tell you yet? I mean, the writing's on the walls here, unless you want some detailed analysis on his thoughts and intentions with those words. In which case i doubt you'll find much help on a site where people come to take a break from using intelligence and common sense.
