It’s also why breakups tend to be initiated by women more often and much harder on men. To women, men are a dime a dozen, while a man is quite possibly losing his last chance at a similar partnership and his children. After the woman has her children, there is little reason to tough anything out. You get a check and the kids when you leave. Even women with children seem to have a better chance at finding a second or third partner then men with none. It’s remarkable.
The balance of power is incredibly one sided, the irony here is the narrative is very different, but that is because we aren’t looking at the full set of facts. Consider for a moment that women literally control which men get to pass down their genes and the power and privilege they exert becomes palpable.
