Oh, I know all too well and personally. I married one. Mine, and much worse, my childrens' lives were living hell as they grew up on far too many days. Its utterly traumatic. I know it when I see it, and I def see it in Rob's behavior, even in writing. Lots of 'swings' in mood, shifting blame, anger etc. His rage towards Fran and the DeLeone letter, at the whole athletic admin (bc he seeminlgly didn't get what he wanted), in contrast to the his admiration for those he believes are on his side.
Classic signs. Narcissism is a very, very real, and difficult condition to treat, as people with it believe by default nothing is wrong with them, and everything is wrong with everyone else.
