dEAR DESP1, I have a question for you: How much do you love yourself??
The answer to this question will determine your answer to the question you posed.
It strikes me that she has a high degree of narcissism. (under narcissism is always appallingly low self-esteem). Don't let her arrogance and grandiosity fool you. Without you to feed her propped-up self-esteem, she would probably hit bottom a whole lot faster!
Again, how much do you love yourself?
sincerely, dandylion
