Intimidation is not something that would occur to me. If she is haughty and stuck on herself, then I'm sure, given the proper circumstances, sparks may fly.
You did not say whether or not I was married or engaged to this woman. So, for the sake of argument, let us say that I am married to her. If she is a kindhearted, faithful, joyful, and inwardly beautiful woman, whom I find to be attractive, then I would feel extremely blessed and secure in our relationship as long as she feels happy and satisfied with a man who is not as intelligent as she is and who makes less money than she does.
Now, even if she is smarter and makes more than me, she will always be in the shadow of my world-class personality. :0)
