These points are true but there's a lot more. Dan stuck Wendi with most of the child care, including being gone at conferences and other events on the regular. I think like many successful men he just assumed that's how marriages work; husbands go out and work and succeed, and wives carry more of the domestic load. Keep in mind that when she published her book (admittedly a low-quality snipe job about Dan and her life) he didn't even read it, because he didn't like fiction. Totally consistent with his being egotistical and clueless about how to treat a spouse decently.
That said, her whole "Danny hurt me" thing is BS. He never was ever physically violent with her, and her intimations to the contrary are totally disingenuous and misleading. They just had a bad relationship, and the fault for that was shared, as it usually is. Might more of the fault have been Dan's? Maybe, but I don't really know and the truth is none of us do.
What I'm saying is, Dan was no saint. He could be arrogant, callous, and totally clueless about how his behavior affected people. I can see why Wendi would want to divorce him. That, however, is where it ends. Her outsized resentment and the emotional violence with which she went about the divorce were totally out of line. As I've said elsewhere in this thread, she and her family became consumed with bitterness toward him, and it ended up destroying lives. We all have bad things happen, but the lesson I take away from this is to just move on, put it in the past, and live a happy life. If you let resentment ripen into hate, it might consume you. It certainly consumed the Adelsons, and look what happened.
