Because they are insane.
You know the Teddy bear thing....that explains the narcissism very well.
The thing is that these men, (and some women, my mother is one of them) are SO cut off from their emotions, that they live their lives as a constructed image...their narcissistic reflection. If they are not real, because they are so disconnected, nobody else can be either. If they don't feel their feelings, how can they begin to relate to other human beings, and whole, integrated, separate people? The answer of course is that they can't.
They are utterly screwed up, inside out, disconnected and damaged. It's dead sad, but the only people who can do anything about it...is them, but they don't because they don't feel anything.
So they are stuck, like Narcissus, as an image of themselves beneath the pool of water that contains their reflections...and woe betide anything or anyone who makes the water ripple....because then...they disappear. Evans called it being "beside themselves". others call it narcissistic rage, but it's not rage, it's terror.
They need to start to reconnect to their own senses, and feelings...and not a single person on the planet can do that for them.
