Yeah why? I’ve earned more then 10 to 20x what my partner earns per year. She also takes care of the house, does the majority of the cooking, takes care of most of the bill paying, sets up my doctors appointments. With the hours I work she is indispensable to me. Plus, she also raised the kids when I was in school and in training and never home. She has earned and still more than earns her cut. Every relationship is different, but just because you earn more means nothing.
