Women who marry professional men who travel often must get used to things like this. An acquaintance of mine who was married to a doctor once got left sitting in the car for 4 hours (before the cell phone days) in a strange city. He went to a meeting and then had lunch with a colleague and forgot he had brought her along. Sound abusive? Maybe, but they had many other good things together.
Makes no sense at all that she wouldn't stop everything until she was satisfied that he was okay.
