I still think some interracial relationships and possibly some relationships in general don’t go well’s that if/when emotional labour’s disproportionately done on one person with little to no reciprocation that it’s going to tire them. If some black men marry nonblacks for validation, it’s going to tire the latter. Especially if they’re often expected to that they’ll get mad anyways.
(Considering there are high divorce rates between Asians and whites, if Asian women are stereotyped as submissive yet some white men tire of them then it’s likely seeking validation from others is going to be stressful.)
Also if female breadwinners are much likelier to divorce (especially if they’re fed up with their husbands treating them like poop), since whites outearn blacks then white women will likelier be breadwinners for better or worse. (In all likelihood, they wouldn’t be submissive and the ones calling the shots whether if black men like it or not.)
If white women are stereotyped as submissive but since whites outearn blacks, there’s a frighteningly good chance that white wives would be the ones bringing home money. (But if some black husbands don’t help them out, they’re going to be just as tired of them as they do with their white counterparts.)
In addition to high expectations not going well (like what if some black men have small penises, are unathletic and lack swag, even introverted and celibate), there’s also the lack of any real responsibility. Though not all black men in interracial relationships are like this, if some interracial relationships do go badly expecting a person to be submissive or receptive’s going to tire them.
Especially if that involves doing a lot of unreciprocated emotional labour that they get tired anyways.
