[The OP wants his fiancee to give up her medical career to homeschool their future children]

Jessica, with all due respect, your focus is on the desires of the wife rather than godliness. Two things. She is to submit to her husband. He is to love her and live with her with understanding. If his convictions dictate that his children be taught at home and hers dictate that she pursues a career then she is blatantly disobeying God and distorting her priorities. If he sees a way to faithfully train their children without compromise and still provide for her to pursue being a doctor then great. But if he leads she must follow. And submission leaves absolutely no room for resentment in the heart of the wife. If she is resentful then she is resentful toward God.
