Example: A couple have gone out on a few dates. One partner decides to break it off. Here is how it often happens (with people who aren’t very nice/concerned about their partner’s happiness):
Man: stops calling. If confronted, lies (‘I was going to call you tomorrow’) and gets defensive (‘it’s not like we’re married or something’).
Woman: wants to talk to the guy about how it isn’t working. Seeks advice from girlfriends - ‘What should I do? Does he really like me? Do I really like him? It’s nice to have a man around. I don’t want to commit to anyone.’ Etc etc. Starts acting weird around him - ‘If you don’t know, I’m not going to tell you.’ Behaves unpredictably and inconsistently. Employs head games, etc.
Now, these are both huuuuge generalizations, it’s true, but reasonably common from what I’ve seen and experienced. And while we have a word for the man’s behaviour (ie Jerk), we do not so much have one for the woman’s (Bitch? Adequate, only). I don’t think that calling men jerks absolves women, at all - we just have different words for the kinds of things they do.
