What's wrong with that cliche

In this episode of what's wrong with that cliche, we discuss "she's so shallow" in the context of romantic relationship. As a person who grew up partially taught only by cliche's, I never actually thought through the statement: "She's too shallow."

Typically, it is said when the guy is unable to gain interest of the girl, or did have it but is loosing or has just lost her interest. The guy will mumble: "That #@%@# is so shallow." The loss, typically will be due to change of object of affection. She will most likely have started liking some one else.

Objectively speaking, there is nothing wrong with that. The other person that she likes is probably richer, better looking, taller, more confident, and better situated than the speaker. Certainly, in today's world, we cannot object to these criterion with which the change of heart is based on.

So... is the cliche wrong?

What does it mean for a person to be shallow? If we cannot challenge the axioms supporting her betrayal, how can we disagree with her actions?

Why ? why does it feel wrong? why do we feel like insulting her with shallowness? The reason why she liked the speaker in the initial place was probably also based on these basic metrics: income, appearance, attraction,... mostly very superficial things.

Perhaps we challenge the deeper in him, the cause of these superficiality. Perhaps we believe that his character, his guts, his stamina, his other things, are not truly as significant and enduring as the speaker's own. Certainly, this is one interpretation of the statement. But even in this case, since the unobserved is unknown, one cannot truly challenge her observations and determination that he's better.

Similarly, perhaps we are concerned that she did not see the speaker's own depth. Certainly, "she's so superficial, she didn't even see my such and such...."

Anyway..., finally, one resolves the offensive thoughts as caused by a feeling of injustice. Perhaps she did, and perhaps she did not know each of our deeper attractiveness's, but what ultimately mattered is that she has taken his bribes, be it fancy words or luxurious gifts, to be more worthy than the speaker's. She has accepted his momentary affection over speaker's persistent affection... This! this!! is the root insult. This is what the speaker is upset with. It is not, fundamentally, in the short run the essence of the two, but the judgment against the speaker's longer, truer, denser, costlier and more persistent love for her.

This is what brings him to say:

"You are soooo shallow!!!"

... what he means is: "Please don't, I really am better than him."
