I see too many people here talking about “because of the inequities between genders in sexual marketplace women will leave her bf/husband for a better.”

I am not here to discuss whether if it’s true or not but the idea behind this phenomena ,i believe, is caused by rationalisation of love and human connection. I believe Wikipedia can summarise better the concept for those who are alien to it.)

Even though it’s just a theory, it seems the idea of hypergamy, dating culture, sexual market value could be explained by this. When you perceive men or women with machine like beings with measurable qualities, the whole idea of loving someone loses authenticity and becomes stiffly similar for each person. You go through similar sets of rules and processes with each person while seeking desirable qualities thus the real life becomes more like tinder each day; you swipe people right or left until you reach the most optimal desired status.
