I mean, once he started having an affair with a women in another country, the rest was pretty much inevitable. I mean, what was he supposed to do, tell everyone he was going to go see his mistress? Oh sure, he could have said, "I'm going to Argentina to relax on the beach. Tell the Lt Governor he's in charge." And his wife (who probably has no interest in hiking the Appalachian Trail) would have said, "Cool, I'm coming too." Like that would have worked out better.
