This field is generally poorly replicated. I have a very low prior that all this "it's just sex" stuff is true. It seems like the sort of provocative explanation that is typical of pop psych. More catchy than true.
Probably more harmful than useful in dealing with what is ultimately the realization that free agents have different objectives and that immature agents are poor determiners of their ultimate objectives.
I guess, when I read the article I was reminded of this 'Game' from Eric Berne's book (https://www.goodreads.com/book/show/49176.Games_People_Play). Could be a reason why (more divorce) if this tension / game was to highlight problems in the relationship.
This is disgusting and a terrible state for the status quo to be in. I much prefer an overbearing patriarchal normal over this cancerous middle ground.
