I have to say that there is something to be said for love from afar, aka unrequited love. It could be said that something like that never gets sullied with the things you regret saying, or things you feel you should have said. It never tips over from that feeling of desire, which is an end in itself – on one level, into the complications of a real relationship. (not that there’s anything bad about a real relationship, of course) It remains in the realm of fantasy, and as a result stays sweet and somehow perfect. I don’t think that feeling ever really goes away. After a while the desire to hang on their every word ebbs away, but a kind of tenderness remains for that old feeling. When you move on, it becomes more nostalgic. I wouldn’t look at moving on as a kind of leaving-behind though, because you never leave yourself behind and those episodes become part of who you’ve become.
As for how do you know you’re “over” someone: You just do, I guess. it’s funny that you should mention this on your blog, Nomes, Cuz it’s been floating around in my brain for a while.
