Human beings are naturally polygamous, whether we like it or not. The word “cheating” is just a shaming tactic, invented by society, in order to have artificial control over a situation. Getting married and expecting the other person to be monogamous is just unrealistic.

It is all to do with expectations vs reality. Most of the time most people have expectations that are not in line with reality. Marriage was invented to control the population followed by the word “cheating” in order to so desperately protect this artificial system.
