It seems to me that a lot of the top posts ultimately bring up the fact that women have more options than men, and thereof they don't feel the urge to find a partner (because in any case, if they wanted to have one, they could easily achieve that). This seems true to me too, but I'm not understanding the reason of this.

One of the explanations I read was that the resources that men provided are not anymore needed by women. But this only relate to survival, not to the only important driver of evolution, which is mating. Why women would have less desire to mate than men?
