Not saying there is anything more to the story, but their kids were hardly that old when the divorce started. Statistically, I have seen that it takes 4 years after the youngest kid is born before this sort of thing happens. Thus I have suspiciouns.
I have to wonder if Hilary thought poorly of Steven as a father. Though that is also the sort of thing you should know after being married for years and all.
@houseoftolstoy This is all news to me and I don't really care. Just offering another common option to your theory.
She got the kids and hence didn't need to be married to him anymore.
And if it was not about the children, I would think she would have pulled the pin before they had children, because it is a really, really bad idea to have a divorce when you have the kids so young. Not unless there are extreme circumstances.
Though that would be assuming she thought things through. And often, women do not.
