You are making a lot of sweeping generalizations that are wildly inaccurate. Some of those statements (hell, maybe all of them) may be true for certain socio-political subgroups of our society, but I absolutely do not agree that that’s the dynamic through which most heterosexual people view their partners (or more accurately, the idea of a partner).
You’re basically just regurgitating the “atomic family” ethos from back in the 1950s.
