I didn't watch but I think you're referring to the idiot that was boasting about his affairs and a random passenger posted his picture on Facebook.
I think it was a horrible thing to do to his BW. It's one thing to find about about your spouses affairs and another for the whole world to know about it. I feel bad for her and her kids. We all felt enough shame, and, at some point in the process, even blamed ourselves for the affairs. This woman will go thru all of that x1000. She didn't deserve to find out that way. The guy is trash and deserves everything he gets from this, but my heart hurts for her.
I know for me, this would make R impossible. I'd feel like I was being judged for giving him another chance after making a fool of me. It's like her path was decided for her.
