What should I do? I rly like him!?

My crush/good friend, called and said he likes my other friend. He wants me to get her to like him. my help. He wants me to convince her to like him. My other friend who also likes him is involved. Here's my prob. I have told him I like him many times but he always forgets. I always find myself in a situation with him asking me who I like. I have been trying to find a way to tell him. But I can't find a way that wouldn't make things weird if he rejected me. My other prob is my parents don't know I have dated in the past. Um not really allowed. I have stuck to not dating for a while, but... I feel rly jealous.

What do you think? What do I say? What do I do? Also, any quotes that well fit the situation? I pretty much hate myself for still liking him...

Thank you in advance.
