Sorry, but it sounds like you both are making great assumptions about dating in general. Where's the proof that women are only willing to choose extremely attractive guys that tick all of these boxes?
The majority of men are average or below, there's no plethora of Greek Gods roaming around, it's probably a very similar amount of males and females who reach that level of attractiveness. I don't understand this argumentation at all, why would all these man be available to an average or below average woman? Same way a Instagram model might not be available to you guys.
I'm sure there's a big past of bad experiences here and it's tough not developing some insecurities, but to focus on just the genetic traits seems like a lot of resistance so one doesn't need to accept something they absolutely need to improve.
Ardour,
He shouldn't put an unhealthy focus on anything, should look at case by case and understand what he could've done better to achieve success. If he believes it's only because of looks and not related to a multitude of things like their age, the type of relationship the girl was interested in having at that specific moment in time, and respecting himself more than trying to manipulate her, he's never going to evolve like a normal person. This is not even touching on attachment theory and all of the reasons why people might put themselves in the position of failing everytime, just to relive trauma, because the familiarity of it is more comfortable than unknown outcomes.
