I'm going to circle back around to the assumption that of course you make more than your partner, but first, I'm amazed at the thought that this would make YOU insecure. As far as I can tell, it's the men who make less than their partners who get insecure about it, not the successful partner! This just seems all kinds of gaslighting, to try and make you feel bad about feeling bad... when there's nothing to feel bad about, in the first place!
Okay, now back to that assumption that of *course* you're with men who don't make as much as you. Is it maybe playing into the stereotype that successful black men want the trophy blondes instead of black wives? So the only ones left would be the less successful ones? If so, that's wrong on so many levels, I don't even know where to begin. Nobody tells the trophy wives they should be happy to have a husband who earns less than them. It's part of the deal -- the husband's money for their looks.
