Right. And if that behavior starts long after you married and had children ????
What behavior are we talking about exactly?
In the real life example I cited above (the crazy woman flipping out in public and throwing a bottle - basically committing assault on the guy) the woman clearly had mental problems.
Are we talking about someone's wife being a stable, normal individual for a decade or more of the husband's personal knowledge of her and her suddenly developing such instability spontaneously without any warning?
If that's the case, then the woman in question clearly has a mental problem like a psychotic break of some kind and needs medical attention.
