It clear that lots of women like validation. You can read about it here and here. Validation is all about warm fuzzies that one gets when one feels desired. I suppose that women when they are young get hooked on this, and many must continually get their fix. So where might the fix come from? Of course, there is straight up validation, but the fix might also come from somewhere else.
One might call it the art of the double negative. The idea is that there is some guy who for whatever reason is targeted as the enemy (maybe he is an ex-husband/boyfriend). She can goad him into making disparaging remarks about her, pick fights with hime, etc. All of this is calculated to give her validation of a different sort; that is, if a bad guy says bad things about you, then one is validated by this. Of course, this type of validation is not as good as the other type, but it will do. Furthermore, it is a different flavor of validation; one might get tired of gorging the same food all of the time.
So what to do if you are a fella put in such a situation? The answer is surprisingly simple: just ignore her. “Ignoring” is about the strongest validation killer known. It might be difficult for some men to do. But men are supposed to be disciplined. So discipline, and a little bit of thinking ahead can turn the trick. Think about this the next time you are in such a situation.
