I mean we don't know anything about the internals of their relationship, and "hitting the news cycle is" I guess just some arbitrary hassle from their point of view. We could suppose that they grew distant, they basically separated, he started a new relationship/affair, and then they formalized the divorce.
Regardless, their money was realistically getting split anyway, so the decision of when to start the affair probably didn't cost him anything.
