Sorry I forgot about his bosse's wife. My bad. However, there is nothing stating that he and the woman in France had a sexual affair. I guess, though, the same could be said for NC with the man in Florida she was conversing with and JP, whom she was naked on her couch with. Why is it okay for NC to have had affairs but not BC. Afterall, she started these indiscretions soon after they got married.
I don't agree with any affairs. I do think Brad had a history of affairs and the last one with the girl in France, on whatever level it was, is more relevant for me. It is just another example of his state of mind leading up to the murder. JMO.
