I love a boy and he lives in the same road as me. We send each other a valentine powerpoint on valentines day he says his was a joke. We sit next to each other in science. I can talk to him when someone is there but when were alone I'm quiet as a mouse! Because I don't know what to say!
I miss him badly on weekends and school holidays, I love him, everyone thinks he fancies emma but no one knows for sure, everyone knows I love him.
Please help what do I do?

Be his friend. Know that that's all you may ever be. Friends are a good thing. Talk to him!

Talk to him as a friend.
