I've been cheated on twice and as far as I knew it was all just sex stuff. Anything else I saw was closer to an argument in nature than anything meaningful, like the guy not giving a shit and being cold and the girl being all like "tell me how you really feel about me!!"...all that kind of drama basically. I kind of sympathise with the guys in a way - all they want is to do is get their dicks wet; they don't want all that baggage and shit for some side action.
