Just like men, women often look for good providers for commitment and financial stability after dating jerks, being attacked for  promiscuity, and even having children. The decent, great-hearted people rejected for not being "tall enough", "thug enough", or "just friends" usually end up being the same people that we seek commitment from because the bad types we chose were too selfish, abusive, and irresponsible to care about us when we finally want to settle down. Unfortunately by the time most of us seek the good men and women for commitment, our value is enormously lowered due to some combination of depreciating looks, financial problems, widowhood, and kids needing  provision.
