In other media, too... we see beautiful people falling in love in movies and TV. We see seemingly flawless celebrities fall in love on and off set. And all these things are not wrong. I enjoy watching beautiful people in love just as much as everyone else.
The problem is... that's usually all we see. Where are the stories of the imperfect people? The overweight, insecure teenage girl and the geeky, pimply, just as insecure boy? We may get movies somewhat in this theme, but the actors always look more beautiful than the average person. And what does this do? It makes girls grow into women like me, who hate their bodies, and find it hard to imagine a guy would ever see through to the inner beauty.
Certainly, it doesn't do this single-handedly. But these images get into our heads, and we start to blur together love and beauty, when they are not at all the same thing. And then, that's what people desire. Perfect bodies, where perfect doesn't even exist. They expect it from themselves, their partners, and their idols. And these expectations feed the cycle. I actually read a comment recently on how an actor's large-ish nose ruined a romance movie for them. Seriously?
This body is tied to this Earth, and whatever comes afterward, we leave it behind. I think that should give you an idea of how important physical beauty is. Appreciate it, sure. There's nothing wrong with that. But above all, look through someone's eyes and listen to their words. That's where falling in love belongs.
