firesong, i've always sensed that you have WAY more feelings than JUST friendship for this person, but were willing to be in the role of FRIEND in order to be around him. there is little more frustrating than unrequited love. now i could be way off base - wouldn't be the first time!!! but you might want to take time to honestly examine how YOU feel so that you can then deal with that. trying to figure out what is going on his head, or anyone else's is a big waste of time. it's hard enough getting clarity on our own thoughts.......
be honest with yourself, and be kind to yourself
