If anyone can show me something in Kate's behaviour which doesn't fit in with this description I am willing to withdraw my accusation, but I bet they can't
Stepford wife"
The term "Stepford wife" entered common use in the English language after the publication of Levin's book and it is generally used as a derogatory term which refers to a submissive and docile wife who seems to conform blindly to the stereotype of an old-fashioned subservient role in relationship to her husband. In addition, it is a woman who is robotic, fitting into a societal role of a suburban mother who is robotic and on anti-depressants. She appears perfect, void of any negative emotions, and has a keen ability to fit in.
It's not a term for a mental health problem which narcism is. I'm surprised that those who post continually about how Meghan hasn't a mental health problem, or that she could have received help in the UK, are so keen on supporting an unqualified diagnosis of what is a real problem for some people. It doesn't help people with mental health problems when terms that have a very real meaning for some very ill people are bandied about so freely.
