He's married... he made an oath, signed a social contract to another person, his wife, that he made the conscious choice to break.
Its clear his wealth generated a level of narcissism here that rose to a level that permitted him to invalidate the feelings of his wife, who, again, he made a vow to.
It does not matter if some hot chinese spy tried to get into his pants. He still let it happen. He his actions spoke for him: "I know i have a wife, but this chinese spy is so hot. I dont care about my wife anymore, but im going to keep this a secret from her because I know its wrong". For a loooooong time.
I'm personally so tired of excusing infidelity. He is a big boy. He can make big boy decisions.
Unless they're a poly couple, who knows.
