This post is so strange. If this isn't a LARP then maybe it's possible that human beings just conform to roles based on resources. A provider makes a decent living but hates being alone. So they bring some dumb useless whore into the house. Then the useless whore wears out their welcome when they act too much like a dumb useless whore. The difference between the man being provider and the woman is that the woman needs to be on birth control to pull this off so there is zero possibility of a child appearing because of this Arrangement. All young people are dumb useless whores, but ask anyone with children and they'll tell you that something just fucking clicked after they became parents and they suddenly evolve to the next stage of humanity.
