Then again, like Babylon Candle says, why is this person so interesting if they aren't attracted to you? I think there's something fundamental about our type that leads us to experience this kind of longing and regret and above all, loneliness, and rejection, but I think we have to recognize it for what it is, an underestimation of our own value. You've got to stand up for yourself. It's natural and healthy to seek companionship, but at the same time, if you are lonely in your own company ... then you're in bad company! You're starting to stink a little. You're not so flimsy that you need anyone else to make you happy. But since it DOES make us happy to pursue new relationships, accept your current situation for what it is, and take the logical next step. Don't say "It's not fair!" Maybe it's not fair ... but that's the way it is. Blame no one, for you have not been wronged.
