A lot of women feel that way (about wanting a child and seeing everyone pregnant but you)
I sense it isn't the full story.
He is an extremely rich man and that means options were available to them that aren't open to Joe Public, fertility wise, if indeed fertility was a factor as has been mooted.
He was already an addict before they split, and photographs from around the time suggested they were enabling each other. Addiction is an illness, and like all mental health issues, takes particularly delight in ruining your relationships.
I do not think that this was a clear cut case of Henry 8th "wife can't get pregnant so I'm trading her in" as some papers have implied.
I think it was far more complex than that and that there were two active participants in the marriage and more going on
But like I said, I really know nothing, nor do you, and I really don't think that having a marriage fail should cost you your livelihood really where would anyone be?
Had he killed that child when he was drink driving that would have rightly ended his career however.
If every man on telly lost his gig for being shite husband we'd lose nearly 90% of them!
