So here. No, besides of creation of a new word-up, this is at least 20 years old, nothing new. And what he does not even touch upon, is that serial cohabitation does not impair character of female partners, but is detrimental to the male. As such, a male divorcee becomes much, much more valuable than a male who is out even of one cohabitation arrangement.
One conclusion he and I hopefully would agree on:
A male of species over 24 that employs whatever tactics to "logically" convince (himself or anyone) that cohabitation without discussion of commitment is necessary for him in order to know "her" is 100% unfit as a co-parent, and will not become fitter. So if "family" is a factor, you should regard cohabitation as a dealbreaker. Tell this to all of your female friends over 24 (or out of education, whichever comes first).
In the day where social media can help people fight Amazon's decisions to profit from delinquents Kindle self-publishing, it's unbelievable that we cannot contain the spread of what has been shown over and over again to be utter societal delusion for decades now. When will we be done with cohabitation truths and lies? It's sad.
