Consider Dispelling With:
The man having to make more money than the woman...
The jobs sector has become a uniquely dynamic climate. Many women in the 21st century will not only make more money then the men they meet, but will have the adaptability to exchange one job for another (sometimes for a higher position) at a much quicker rate. This is not, (should not) be a hindrance to a union of different economic powers if his ego can take this set-up and if she doesn't continue to rub this fact in his face, as a deliberate means of emasculation. Both lines of rhetoric will do more harm to you as a couple, especially if another woman comes along to boost the part of him that you have been cutting down - his ego. Or if another man appears for her that is financially secure or happy with what he makes.
Him having to be more intelligent...
If the main purpose of your conversation is to have academic debates then tell me right now to shut up! But if she has a PhD in thermo dynamics, does he have to have an equivalent? Personality and sustainable chemistry are key to a good match, not your qualifications. And don't underestimate the unlikeliest of pairs making quality couples, for reasons of curiosity and balance the unknown, the unfamiliar can be a long-life aphrodisiac.
The notion of the house husband being an alternative lifestyle...
Probably the toughest one to sell - even to myself because I have career goals, but your 'he' may not. He may have a part time job or just a lifestyle aim that is different to what we perceive as the norm. If he is cool with being a house husband and you are too or it just makes more sense for your partnership to operate that way, then what is holding you back?
Who gets a say in how your relationship is run...
Remember it is you two living together, as one unit, your friends and family are not facing your daily emotions or challenges and if you find that external opinion and insensitive interference is causing you grief, you need to make anyone deriding your lifestyle understand; that it is not up for mockery or immature discussion.
