Just from physical power alone, this is how things evolved. But then you have Serena Williams, a very physneed. powerful rich woman, and she chooses the guy that made Reddit, a cute little doughy guy. She had everything already, and she chose this kind, sweet, intelligent, loving, little computer nerd. At the end of the day, the ultimate choice is happiness.
I think women just want a man that can get shit done. Being in a relationship is like being with a battle buddy in a war, if the guy you're with, that is there to keep you alive, starts to panic, fuck things up, make mistakes, shows incompetence.... You aren't going to feel to secure and you are going to want to be put with someone else. Women don't want mean, evil, or bad men. But they need men that can keep them safe from he world.
