Avirah, your understanding of this Rambam is not meduyak. You added in your own hagaha (idk where you came up with this) that ‘ohavah kefufo’ doesn’t mean love but rather providing. This is a false interpretation and a real twist. 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. Also, the woman’s need to feel loved is more integral to her than it is for a man. (Not saying men don’t need to feel loved sometimes, but I think anyone who is married [and I’m not] might resonate with the reality that the wife sometimes experiences different emotions and expresses it differently based on circumstances.)
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.
