There is an excellent blog here at FFF by Mhayonaise on why men cheat. Here is a take on why some women do.
Narcissism is excessive vanity. It involves fascination with one’s image.
The conventional wisdom is that infidelity can be a natural result of narcissism. Society conditions women to have a need to feel beautiful, so they look in the mirror. If the mirror is a cute devil, that’s the show.
There may be other reasons, mostly due to the fault of the man, but I leave it to others to dissect them.
Recall that N was famous for his beauty, and he even attracted men. So, it is not surprising that gay men are typically narcissistic, and also promiscuous.
But it is a matter of degree. All of us have a bit of Narcissus in ourselves, so a little does not make for infidelity. A lot obviously does. According to health experts, less than 1 percent of the population is narcissistically unhealthy, and of those, only 25% are women.
Since men are more likely to be narcissists than women, they cheat more.
There are exceptions to the link between narcissism and cheating. One is the “cerebral” narcissist, who is not into sex. An “intellectual” woman absorbed in her image of her mental powers is therefore an exception.
According to experts, you can tell a narcissist by the extent to which they behave like a “spoiled child.” This is the two-word test of narcissism. I’m not sure that if a person has lots of pictures that she is a narcissist. Maybe what she does with those pictures is something else.
