Well it's hard for me to write now. He's all I can think about.

He's the nicest guy in the world
He is so sweet when he phones asking for my brother and end up talking with me for an hour instead.
Last time we talked was a couple of days ago but I still havn't forgot his voice.
Every time he's over and my brother is busy for a few minutes he talks to me or wants me to play CoD head to head with him.
Now we go to the same school and he promised me he would look out for me so I wouldn't feel alone.
When he sees me he runs up to me and asks how my day has been.
He said that he would always be there for me if I needed someone to talk to.
He is one of my brother's best friend and I've known him my whole life

Do I love him? Yes I do.

But there is a problem.
He dont think of more of me than a little sister, or I dont know that but he has a girlfriend so I doubt he do...

Can anyone with the same problem help me?
