In "Dating Narcissistic and Egotistical Women," dehjomz asks the following about the decline of respect in a relationship:
“The problem I've faced is that I've ended up liking certain girls a great deal, but they have turned out to be selfish, cold, domineering, and narcissistic. But they were not that way in the beginning! They were quite charming and submissive and appealing to my emotions...which is why I selected them in the first place.
But unfortunately I've consistently suffered from the 1-year drop. Their charm fades, they become comfortable, and and then the real selfish, arrogant, dramatic, neurotic sides come out. I'm pretty much the same guy all the time...until faced with disrespect. In the beginning they were much more influenced by my words and my power and complied with what I wanted. But after the 1-year drop, they become more dominant, more readily resistant to my power, and instead do whatever they wanted, whenever, without any regard to my emotions. Hence arguments. I've tried everything, and no amount of logic or trying to frame things as "we're a team" works or changes the situation. They just don't care and instead they try to justify their rude behavior instead of showing empathy toward me and understanding why their rude behavior makes me mad and why I cannot tolerate it. They want to get their way, and they could give a fuck less about what they say or do to try and get under my skin. Being calm and ignoring doesn't help because I'm left wondering how this woman could have the audacity to act this way, to me of all people?”
My response was, while this can happen with narcissistic women, yes, it can also happen with any woman - even women untouched by narcissism.
This is not solely a problem with the woman. It's quite often a problem with the relationship.
That is to say, what often happens with men is a general, gradual decline of respect in that relationship, where women come to view a partner they originally saw as powerful, dominant, sexual, and strong, as possessing less and less of these qualities... and more and more of their (distinctly unappealing) opposites.
The relationship falls apart and fails because the woman has stopped respecting the man - even if he hasn't changed a bit.
