Men can achieve their primary objective without marriage. How stupid can women be?That's pretty true biologically. Sex does drive guys emotions and motives. It's the way we're built. However, that's only half the equation. A roommate is not a wife, even if she's a very "accommodating" roommate. You can't make a "home" with a roommate. You need the defined and understood continuity that comes with marriage.
Believe it or not, the best way for a women to corral a reluctant-to-commit guy is to get him involved with kids (niece, nephews, Little League, etc.). He'll either realize what the secret ingredient to "home" is (wive+kids), and want some of that immediately, or he'll flee like a scalded dog. Which is OK, because women shouldn't date scalded dogs.
Thats manure, respectfully I disagree. The problem with your theory is will and does come across as manipulation or trickery. Thankfully men have become more aware of such manuvers. You don't need to point that out, we know it already.
I had a girlfriend try that before I knew her enough. Considering the sneakiness of the stunt. (I did discuss it with her and she did admit why we were suddenly spending time with family and people with kids) Less tricker more communication. (ie he wants intimacy every day she's a once a week gal)
Men know what they want beyond just sex. Women have forgotten how to be women. Now men and women are paying the price for that ignorance.
