“Dissing your man to other women lessens the likelihood one of them will try to poach him.”
Or maybe one will think, “I always thought he seemed like a nice guy. If that’s how she treats him, maybe I’ll make a play for him”. Could happen.
Women know women. If one is constantly disparaging her man, then of course other women will wonder if it is because she is driving off the competition.
If a woman really wants to get rid of the man in her life, then of course other women will understand that she will make him out to be the next thing since Carramundie’s Crunchies, and pass him off gratefully (sp?) to the next girl in line.
But to the general public...
To anyone other than her trusted friends and family, of course she will never tell them all about what a catch he is...
All others do not need to know. :)
