What you’re describing sounds like a difference in mate value. It’s a combination of any desirable traits like looks, fertility, resources, or anything else. We might spot an apparent difference in two mate values, but the US doesn’t have many rules or norms around mismatched pairs. Other cultures might though, with rules around bride price and such.
Most animals are pretty good about assessing their own mate value from physical and social signaling and tend settle into matched pairs more often than not. There are some cool social experiments that repeatedly prove this out, but I don’t have any links handy.

Regardless what’s going on with your friend you posted the same long screed in 6 places.
I’m gonna be real enough with you to say that behavior is screaming a big need for external validation. Or at the least, a marker for high personal drama. In my experience, those friends will wear out my social battery real quick and “it’s too much to hang out with me” is exactly how those folks can feel.
I honestly wish the best for you, your friend, and any friendship y’all manage between you. Just don’t forget to monitor the emotional load that you’re asking folks around you to carry.
