The longer a woman knows a man the less important his looks become and the more important other qualities become. This has been studied and has been shown repeatedly in study after study.
I agree that a lot of relationships are not running off of looks alone, but why would any rational man want to be in a sunk cost or transactional influenced relationship? The genuine interest from the girl is gone, she is constantly acting masculine, she is more prone to cheating & manipulating the man, dead bedroom relationship, and etc. I would rather date a 7/10 that is submissive, feminine, and conducive than a 9/10 that confidently knows that she can do better than me looks or fiscal wise. Last, these relationships are speculative at best. You do not know what if the guy had a higher smv during the budding stage of the relationship and lost smv as the relationship progressed. At the end of the day, women are humans just like us, so expecting them to operate on some fantasy mindset is purely delusional IMHO. I am sure guys like Rick Ross and Donald Trump can get laid, but I would rather be Micheal B. Jordan or Chris Hemsworth dead srs.
Last, I just want to state that I am talking about relationships with obvious SMV disparities. A lot of couples are actually pretty even looks wise, but factors like makeup, over-valuing women due to being a man or dry spell and undervaluing a guy's smv because he doesn't fit the typical stereotypical Chad Greek Body masculine frame look lead to us thinking that the guy is pulling above his weight.
