This is the end of the planet of monogamy. The imagination of relationships to death, is shining before our eyes

We are not told that a man after the birth of a child, at most will be number 2 in a relationship, that these bonds -- in most cases -- will slow shift to common indifference.

That tenderness will be replaced by contempt, emotional coldness of a husband or wife.

We are not told that most people who are now married or partnered face betrayal. And it's more than one.
