Please help? I miss him soo much x?

Well i'll start off with how we met.Im 13 and i think that he is abouts 14 or 15.We met at this wedding (he's a family friend of mine).I know his sister and his little brother very well but i never knew that they had a older brother and i never bothered to aske either.So at this wedding the first time i saw him I ended up having the biggest crush on him ever.There was a chocoalte fountain at the weddig but there was no one there ast the time.He was standing there with his little brother.I was going to take a cookie when he started teasing me and saying we were not allowed to take it .I told him I didnt care and i picked it up,and said'haha' and went.He was proper fit and I think he likes me too.I caught him staring at me from the corner of myy eye.I was sitting on the chair and he went and stood right behind the chair i was sitting on.Then later he sat right opposite me and he was smiling.Oooft maan.Then he killed it.He gave me eye contact and when he did I didn't notice anything else happening around me.Just his eyes.But the thing is i blew it big time,i havn't seen him ever since and i dont have his facebook or msn or anything.I love him so much but i dont see any chance of being with him or even seeing him again.I knwo that after reading this you probably will not bother to answer but i really need advice.Please?? some one :(
