We've been friends for ten years. Recently I started to think of him as maybe more than a friend. I don't really know what to do... :/ And that's pretty much it.

Be honest with your feelings but don't limit yourself to just him. He may not feel the same way, or your interest in him may fade.

What about him? Is he a single too? If the answer is yes, you should tell him how you feel (that you are confused, may be you like him more than just friends). A ten year old friend will understand you better, and he will let you know what can be done.

A friend for ten years might like you but if he doesn't don't beat yourself up over it and if he is a good friend he will understand and everything will be OK.
