I would like to make it very, very clear that I am not advocating the pathologizing of victims. It is very possible to be schmoozed and fooled into believing a narcissist is Prince or Princess Charming who then, once you are dependent on them financially and otherwise, will show you the fangs behind closed doors. People can unwittingly be caught and trapped into relationships with malignant narcissists. I hope you saw my consistent use of the words "choice" and "will" and other iterations of words which clearly showed I am referring to people who can and are able to walk away from a situation.
I would also like to state that very often there are ways out of a relationship with a narcissist even though it may look like a hopeless trap. It may require stealth, careful planning and lots of time, but a way can be cleared to make it out as long as you're not chained in the basement or have a gun to your head. I have seen more than one trapped adult who appeared to have no options think their way out of what looked like an impossible bind. Difficult does not mean impossible. While it is cruel to pathologize victims, it would also be cruel to say that victims must remain victims.
My father is, again, an example of the kind of person I am describing in this post. He is not financially dependent on my mother. He is amazingly psychologically independent of her as well. He lives a very social and active life apart from her. He is an accomplished and avid fisherman who has built a camaraderie of friendships around this hobby. He plans long fishing trips with great frequency which gives him many blocks of time away from my mother. He remains in his marriage with my mother by choice. He could walk away and she'd only get half of what he owns...and half would be plenty to live on. He isn't even a religious man; so religious compunction is not dictating that he stay married to my mom. There is obviously a symbiosis. He is getting something from this close association with my mother and her evil. While it is rather mysterious and unknowable from outside their relationship (though I could come up with some good guesses)...he is getting something for himself from staying with her. He can only stay with her because he is morally compromised himself. His lack of integrity and moral straightness becomes evident when tested against my mother's overt bad deeds. He excuses, rationalizes and ultimately supports her bad deeds by renaming them. He proves his corruption by his acquiescence to her evil for the sake of his quest for peace at all costs. He consistently chooses easy over right. I have a boat load of evidence to prove he is in this marriage by choice.
When you can walk away but don't...the reason lies inside of you. That is what I'm challenging people to look at in my last post.
