To play devils advocate here, this was at a time before to no-fault divorce. For a woman to divorce her husband she was forced to show just cause, such as abandonment, insanity, adultery or cruelty. Cruelty is the easiest to claim. he obviously was not insane, he had not abandoned her for a extended period or to the best of my knowledge been in a affair to she would have to claim cruelty true or not to leave.
