Yes, you are way smarter than her. I agree with you that

she should have left that doctor once she found out he was not loyal to her. If she was my daughter, I would force her to do that.

I said that she has high self esteem is from other details that she describe her personal life. Such as, she never think that herself is any lower that the surgeon in spiritual level, even she is much poorer than him. She refused to watch sports with the blond... ect. The doctor is a not a good guy in our eyes, he like to sleep around, but she doesn't like to settle down as well
