How can i kno,he likes me or not/he wants to take me in a date or not,how can i attract him severly?

He is 14 and me 13.He doesnt talk or flirt with me.He mimices me a little bit. I gave him 2emails in facebook but he didnt reply.He is really y.He is my 1st and last true love though he has 3girlfrnds.May be i m not hot like his gfs.I m confiedent,my luv can change him.One of his frnd told me to ask him out and they think he will not say-no.But i want 2 hear from his own voice to take me out.How can i attract him severly.
