if your crush knows you like them AND they like you back then you can gradually talk about dating them. if they have said they dont like you back then dont bring it up again
Because he knows you have a crush on him, and you probably show it more than you realize.
You should go tell him that you like him
Of course not. There is not a 100% chance that your 'crush' even knows you
The world might end. No, but seriously why not just talk to the person? Who knows maybe they like you too.
Okay, I think I followed this; yes, if your crush's friend is asking you if you like your crush. YOUR CRUSH IS DESPERATE! otherwise he/she would probably try to keep cool and find out themself. I think this means your crush likes you.
Either to tease you, or because he secretly does like you.
Maybe your crush might like you back, but don't know what to say, or they might not like you and are avoiding you, or might be uncomfortable talking to you knowing you like them.
Most likely
act like your not bothered by it.
You send her a note that you like her and talk to her see if she go on a date with you
take her gently by the hand and ask her when your alone with her <3
