Avirah, your understanding of this Rambam is not meduyak. You added in your own hagaha that ‘ohavah kefufo’ doesn’t mean love but rather providing. This is a false interpretation. The Rambam already says to provide, this is in addition to providing.
Why a woman is not instructed to love her husband could be because it comes naturally more for a woman to love her spouse than it does for a man. (Or more specifically, that a man carries the greater imperative to initiate his show of love.) And there are several examples in the gemara of Amoraim who placed significance on a certain level of ‘romanticism.’ This is a whole different topic though.
Regardless, the halacha is clear as it is stated. It might be irrelevant for most people, but I just wanted to point out the specific obligation inherent in a Jewish marriage for those who might have thought otherwise.
