I am not so sure 'narcissist' is the correct label here. In my own experiences with them, their methods of coersion are more subtle. They use a combination of charisma, charm, and passive aggression to manipulate those around them. Yelling and screaming does not fit in with this. I am unsure what personality type you would assign to this individual.

But a label does not matter.

I do have some questions though as I am trying to wrap my head around the context here...

Does this person behave this way across the board? Are others treated in this manner? In what way do they react? Have you been able to discuss this with anyone? Is there someone you can confide in? Is there someone that can act as an advocate on your behalf if you were to confront her?

For many of us in an abusive situation, staying with the course is sometimes less frightening that making a leap to enact change. It is a case of the known being maybe easier than the unknown. This is a trap many - myself once included - fall into. It is why people stay in such a rut. I am really glad to learn you are then getting some resumes out. I would make other contingency plans too.

I wish you best of luck with this situation. We are on your side.
