I personally feel that deep down the vast majority of heterosexual women desire a man that will ultimately be able to support her while she stays at home with her children. I feel that things may be a bit different when she is single and childless, but based upon my observations I feel that this changes once she becomes pregnant with her first child. Certain hormones are triggered and she is biologically primed to be raising and nurturing that child. Our current society has things set up where being a stay at home mom while the husband goes off to work is just not possible financially for the majority of Americans/westerners. Women have been programmed to think that they don't need men and that they should go out and be competitive in their careers. There is a reason why female ceos are seen to have far higher incidences with depression and other mental health issues, as they are operating on a masculine wavelength which is opposite that of their biological programming. Granted, there are naturally exceptions to this but very few women will truly be happier with a career focused life of being single compared to that of having children and being supported.
