Not sure if this is a controversial opinion but if the wife decides to divorce the husband based on what ChatGPT says, perhaps the husband is better off.
Which.. sounds like she was either just looking for any excuse to divorce, or she was already divorced, from reality.
There is no story here about ChatGPT, this could have been anything. It could have been the way a dog barked, or hidden messages in the radio, which we wouldn't associate with dogs or radio.
If we are going to attempt any deeper analysis from this, it should be an analysis of what services are in place for people with mental health issues and how people can be empowered to notice signs to help their loved ones.
This sort of self-radicalization will only grow. I've already seen too many cases of "chatgpt told me that I am God" in weird corners of reddit.
