You got it backwards. Taking care of your other half when she needs it is an expression of love and appreciation.
I'd love to revisit this conversation when you're in your 70s at some retirement home with a bunch of strangers and "caretakers" who see you as just another number off their list. If you're lucky you might get 2 showers a week
Humans are supposed to establish familial bonds and to become interdependent. I'd rather be taken care of by ppl who actually care about me and view me as a person than some cold, impersonal system. And if you think that your wealth will guarantee good care then you're very delusional. Nobody respects a millionaire who can't even tie his own shoes or speak coherently. They won't be changing your diapers with a smile breh
