Women voluntarily pair with men, (a) to defend against involuntary pairing with other men; (b)to gain access to resource and defense, (c) status (market value) largely among women, (d) to capture genes, attention and resources and keep them away from other women, (e) mates will sacrifice more than all other combined except mothers for children (ie: friendship), (f) cooperation is disproportionately more productive than all other individual actions.
This produces the emotional reaction of friendship: ready access to attention and care. Our emotions evolved to inform us that these are the optimum actions.
Marriage is only an optimum under property. As we can see reversing in modernity. Successful people with assets stay together. Poor without them far less so. I can explain that also but it’s not very ‘nice’.
