I have no idea what your point is supposed to be. The dude is married & he's arrogantly flaunting his infidelity in public, that's a capital marital crime in my opinion. Her status as divorced is wholly irrelevant, she presumably knows he's married so she's a disgusting fucking pig.
The guy's divorce will be forthcoming? Yea? It sure as shit will be, that somehow absolves him?
Like I said, marriages fail on the daily, but this isn't what you do in the face of a failing marriage. Man the fuck up & leave your wife in dignity rather than, in this case, making a world wide spectacle of yourself and her. In the far more common non-public case, you still humiliate the shit out of the spouse you're cheating on and that is some painful shit to swallow when you're on the receiving end.
