Having a bit of a think here with the whole Steven Crowder getting divorced. He and his wife were married for a number of years, and the moment they have kids, she divorces him.
One theory is that having children revealed cracks that already existed in the marriage, as having children makes everything more difficult. But it still seems strange that she would not have divorced him sooner.
Side note, having children involved makes divorce far, far worse.
@PapaPole If it is true that he is unpleasant to live with, that should have been apparent before. Which is why I think that the children coming into play is the biggest factor. I don't know everything about Steven Crowder, nor if much of the rumors are true. But there was likely something that made Hilary think that he was not fit as a father.
Just a theory though.
