All right, I'll go ahead and name names because neither person is here anymore.
I've been on CC since 2009, and early on, I had a severe crush on a user named Matthew (yes, that was his username.) The funny thing is, I had a crush on him, he didn't have a crush on me; I accepted that it would never turn into anything, and then something changed, but by then... I had come to see him as a friend. And so, it just never went anywhere and we lost touch.
The other user I had an attraction to, as in, I would have loved to have met him, was Nuke Pooch. We talked a few times and I did tell him I wish we could see how we got along in person. But he didn't feel the same way, and we too lost touch along the way.
I'm sure the anticipation is high as to who my next victim, er, object of affection may be... but truthfully I don't get crushes too often and I'm at a point now where it would take a long time and would probably have to involve meeting in person first.
