Do You Agree On That Theory of What Most People Say About Cheating?

I'll like to say that I don't justify cheating from both genders, but over the years society tried to teach me different reasons why women and man cheat. You can hear the most common reasons that a women only cheats with emotions and it's mostly the man's fault because he stopped being emotional attached to her, so she had to cheat, and in the other way around you can hear that man only cheat because they just want to have sex with another women for fun, so it's still their fault for doing it. But isn't that theory mostly a big disadvantage for women and not man? If women actually cheat with emotions that means that they stopped loving their partner and makes them even worse as a cheater, but if a man cheats because of that sexy women for fun, then his emotions are still attached to his wife, so he can still love her the same.. What do you think about that?
