I've found that my setting any expectations of "more" is self-defeating, if nothing else. Relationships of whatever flavor have to just flow in their own natural channel, wherever that ends up.

That said, I don't see that I have all that much to offer to just-friends, because absent the deeper emotional connection, or a loving relationship, I tend to keep my walls up and not be completely myself. There are a few exceptions, but not many, and overall my life is dominated by the big-R connections?
