You have a source for these queries?
Never heard those points against him. I recall reading that he was caught cheating on his wife.
In the divorce he gave her half of everything they had built over the years together, with out nasty things being inflected on each other in the courts.
He also requested ( and I believe was granted by his wife) that the family still spent holidays and other important family functions together .
It was a joke. There was a very funny Saturday Night Live skit where they portrayed Neil as really over the top. I always thought it must be because they couldn't get him to appear on the show or something. I have always loved Neil Diamond's music and I even bought most of his 45s back in the '60s.
