RP says to flirt with other women to make their wife or gf jealous which will somehow make her want to jump his bones because of dread or preselection AKA, oh no he might leave me!/ooh other women thinks he's hot better fuck that D!

This doesn't match my experience at all. An ex started to pull this 2 yrs into our relationship and I felt only disgust and anger at his disrespect. That is why he's now an ex, even though he begged to get back together and swore he would change, blah blah blah.

It almost seems like older guys giving this advice are trying to mess up younger guy's chances with women, like they want them to fail.

I dunno, is this kind of thing hot to other women? Is it threatening enough to make you do duty sex just to keep him? To borrow a RP phrase it just seems low value and disrespectful to me.
