I'm so glad that her post went on to explain that the fact that they ARE "opposites" means that the love affair is both hot... and likely to be doomed.

I do beg to differ on the POV that only doomed relationships are interesting. But I suppose that she means "interesting" in the sense of crane-your-neck-to-watch-that-traffic-accident interesting. New love is about desire and exploration and working out the rough spots - love that's settled into trust and a steady, warm glow isn't exactly eye-catching, even if it's what we all want.
