From Kathy Krajco's blog:
Perhaps the strangest thing about narcissistic abuse is the almost universal decision of the victim to put up with it. This is something other people cannot get their minds around. And it is one reason why they withhold sympathy from the victim, blowing off severe psychological abuse and mental cruelty as mere annoyance.
But there are many understandable reasons why the victim puts up with it. All people need do is think a little to understand.
I know that many of you who read here also read at Kathy's most excellent blog, but just in case you missed this one I am pointing you in the direction of this post. She captures the fundamental reasons why children of narcissists are especially vulnerable to putting up with the crap that narcissists dish up. She does this without pathologizing the victim. God bless ya, Kathy.
