I’m not blaming him – this is a fictional story, so I don’t want it to sound like motzi shem ra on him. I’m sure that no one who ever read his books got divorced.
Let’s say a fictional author wrote a fictional book about marriage and it had the name of someone divorced in the cover – that would make me nervous. I’m not saying it’s necessarily rational, but emotions don’t always have to be rational. The whole idea of giving your Kallah a diamond has to do with emotions, not rationality.
