I met this guy, but I met him on my friends Facebook it sounds kind of creepy but every time he talks to her I talk back and she lets me because she don't like him like that just as friends so he thinks its her, but now the things I'm saying to him on my friends Facebook is making him like my friend, its almost like he doesn't even no I exist but just the way he talks and how nice and cute he is made me like him even more, now I don't know what to say to him,I have him on my Facebook but I'm way to shy to talk to him, And every time my friend brings up my name to him he always says he doesn't know me... I just like him so much that I can't go a day with out talking to him but at the same time I'm getting him liking my friend even more because I'm on her Facebook, the more he likes her everyday, I just want to cry it makes me so upset because I can't talk to him because I'm to shy... someone please help me I don't know what to do PLEASE HELP?

Why don't you get your own Facebook page and add him then explain the situation too him. IF not ask for his phone number. I'd suggest explaining this complicated situation

I have him on Facebook but I'm wayy to shy to explain or even talk to him

So your saying that talking to him through your friends Facebook gives you the confidence you need?
You won't get anywhere until you get the confidence to talk to him on your own.

Well me and my friend are going to her boyfriends brothers grad party,and I'm going to work up the confidence to call him after the party is over to come pick us up and hopefully when he picks us up I will be able to tell him. Should I do that?

It's a start. See where it goes from there.
