His friend asked if I like him?

ON FACEBOOK; His friend asked me if I like A ( surname ). technically, yes I do, but, I don't know why his friend ask me that kind of question, Well I don't even show any sign to A that suggest how I feel and I'm not sure what he feels about me.His friend asked me if I like him and if I need his help for further actions, which means, if I want to couple with A he can adjust it for me. I was like.. what has happened? I said NO, and later... his friend told him that I like him. I know his friend was like joking but then when I look at his profile on FB and his status was ' OMG, THAT WAS THE HAPPIEST MOMENT IN MY LIFE'

Can you guys explain that to me ? what does that supposed to mean? If you barely can't get what I say, just ask me for extra info.
