Nature and social conditioning are two different things. If it was innate for women to be the way you describe then, there wouldn't be the need to "socially condition " them. It's good to understand the concepts before trying to raise a point.
If we look at the primitive societies ( there are still some vestige of them today) we can see that in those places, the women do not only do the whole maintaining of the house and taking care of the kids but they are also the ones who work the land and tend to the animals. In many of those societies, the men do close to nothing. So other than the idea of men providing a sense of "security "and mating to make babies, these women do not "need" the men. In these societies having a man is mainly a social statement on which women are judged for. Rather and actual need much less a desire.
So yes, I agree women have been socially conditioned to put men's needs above their but there is nothing natural about that. This can better be see. in countries where women no longer depends on men to give them social acceptance. Just so you know the US is not one of those countries.
