It's probably Narcisstic Personality Disorder, with a Psychotic Break. Like I said, there is no for sure 'lab test' for psychiatric diagnosis. Whatever it's called, he 'lost' it. I have seen a few cases where the woman leaves her husband for another woman, and that seems to bother the guy more than if she left him for another guy. I know 3 men that this happened to, and they were all very angry men their entire lives....didn't want to date women again etc.
