I can't imagine any of the royal men don't cheat, honestly. While the norm of a man having a mistress and it being simply accepted went out of fashion for the rest of us, it's a different story for the upper echelons of society.
It's only with Charles and Camilla that the public saw and judged the behaviours, but even then the only deviation from the norm was the backlash. I feel like William and Harry learned to be more discreet, but I'd be shocked if they learned not to have a mistress.
In that situation their wife makes a choice to stay or go. I don't necessarily agree with their choices, but I also have no inclination to live in their circles, so perhaps for them it's worth it, whether in the relationship in other matters, the position, or even if it's just them also getting to have someone on the side.
