"Just because you can sense something doesn't mean you feel strongly compelled to fulfill the will of its source. " Yes, agreed, an Empath is not necessarily a co-dependent, nor is an Empath necessarily willing to be compliant, tolerant and forgiving toward a Narc at the Empath's own expense.

Haven't seen a generally-agreed upon definition, but I think an affective empath is basically someone who gets a read on what is going on with the other emotionally. With regard to a Narc, an Empath might pick up on insecurity, shame, hate, envy, greed, possessiveness, false outward emotional expression, and so on. An empath would not necessarily feel a need to attend to a Narc's welfare. In other words, being affectively empathic does not signify a prosocial orientation toward an enemy. I think the analysis is pretty much the same for Cognitive Empathy and the Affective variety. For all of these reasons, I have a problem with Tudor's language.

Tudor writes and speaks regarding romance, and I think he conveys accurately what he has encountered. The "empath" may be a female or a female type in love. An intellectual approach to this matter of narcissism would be different. However, there are a number of reasons why it may take a long time to get a fix on where the narcissist is really coming from, which is for reasons that Tudor also accurately outlines. One of these is the narcissist's very effective facade, which is his generation of an appearance of social sensitivity. This could not be further from the truth. It is made up up borrowed cloth. Also there are many ways of thinking that are totally counterintuitive to emotional cognition. The most fundamental of these is that narcissists reverse the direction of cause and effect. Specifically, if someone has been affected by something horrible -- let us say that there loved one was in a car accident -- the narcissist will suppose that the horrible thing was something that the car accident victim bought on themselves. The narcissist also has the counterintuitive reasoning that if one expresses empathy for the pain suffered by one's relative in the car crash, that one is revealing confusion about one's identity -- or, worse still, trying to steal the identity of the car crash victim.
It takes an enormously long time to examine the narcissists behavior and reasoning, based on their "tells". One has to be really dedicated to the task to figure any of it out.
