His wife dumped him, because he was too introverted. He did not want to get divorced, but agreed to it and did it without lawyers. He basically gave his wife everything she wanted, so as to not put his daughters through any bitter squabbling. He never even hired a divorce lawyer, letting an arbitrator handle everything.
About a year later, his wife married a multi-millionaire garment industry mogul.
I had always heard that he dumped her, but I can see why she dumped him, if that is the case -- it sounded like he spent all his time down in the basement avoiding his family! Funny how he now goes out in public all the time with the bimbo girlfriend, when all he wanted to do when he was married was avoid everyone.
