From my perspective, if she were my daughter, I would caution her about marrying you. You said that she had other problems with your Rebbe, aside from not feeling comfortable with him. She explained it to you, but you seem to lack concern for her feelings.
Keep in mind, no one, not even your Rebbe is perfect. I have seen some Rabbonim give very poor advice in interpersonal relationship issues. Your Rebbe may be just fine in the Halachic area, but it doesn’t mean he is suitable in every other way.
I don’t feel that you’re mature enough to make that decision now. Speak to your parents about it. I’d bet the girl has a very valid point and has insight that you don’t.
If you can’t consider your wife’s feelings about this, you will probably have that attitude about other things as well. If you want a successful, happy marriage (no matter who you marry), you need to think things through better and mature a little more. In real life, those absolute gender roles are never absolute. A successful marriage is a partnership.
