I think it's understood that women prefer to fuck alpha Chads but marry a more stable beta mangina provider. However, women also tend to want the best of both worlds, i.e. have their cake and eat it too. So what do they do? Wherever possible, they marry the beta and then cheat so they can have Chad's more beautiful baby. Does this make sense? Or if they are forced to have the beta's baby, they resent him for it and treat him like shit.
