I think you got it on the nose when you said "jerk". Who goes around responding to their basest desires (then calling it love on top of it all) with no thought to how it affects others?

Who doesn't sometimes feel lust for people other than our partners? Even Jimmy Carter admitted to lusting in his heart. But you are married or committed to someone or civilized for goodness' sake.
