How many times have we seen stories based on "former aides", "sources say", etc...
But to be honest, this is 1 story I would actually be more inclined to believe. His marriage to her lasted very long. Longer than the typical millionaire playboy type length. I'm even convinced he did at some point cheat on her. Before being president, he has money, fame, power. I'm sure pussy was being thrown at him. It takes a very strong man to decline it all.
Just hope if he does become single, he better be wearing a body cam and have cameras in his bedroom. Lots of women would look to blackmail him.
