Women like this have a supreme need to bask in the light of what they perceive as greatness, because it is that which gives their own existence substance. Like those with Narcissistic Personality Disorder, their actions are the result of a personal emptiness that they are psychologically compensating for. The spouses of women like this - unless superhuman - will always be at risk of being left behind, because at some point they fall off their pedestal and thus lose the ability to provide the kind of greatness by proxy that the borderline requires. It's like needing a bigger and bigger, or at least newer and newer fix. If you look at all the pictures of her that have been pasted into news stories, they have a general feel of flamboyance - of someone seeking legitimacy and attention. Women with this personality disorder are self-destructive, and even cut themselves.
I'm not in any way excusing Petraeus. He made bad choices, and lost his self-respect, his position, and hurt his family in the process. He followed the ‘Song of the Siren’ to where it usually leads - self destruction.
I agree. I was married to one and was the sister of another.
Best reference, IMO: “Stop Walking on Eggshells”
