I Have a big crush on a boy who's a year older than me (he's fourteen, I'm thirteen) and he knows. I only see him for about 20 minutes a day, but him, his friend and I talk together a lot. He's really funny, smart and friendly, and when he found out that I like him (a friend of mine told him) he didn't act any differently towards me. I thought the crush would go away after a week or so.. . It's been half a year. Id really like to tell him myself that I like him, but sometimes I just think that it's pretty much hopeless.. . This is the biggest crush I've ever had, what should I do :/

In view of the "my friend told him I like him" angle I think this should be on the teen board.

Do you talk to him? Do you have contact with him, an opportunity to talk to him? Trust me, if you talk to him and he "likes" you, he'll let you know.

Moved to Teens due to the OP's stated age.

You have to talk to him. You will regret it if you don't try.
