In a just society, there should be capital punishment for cheating. It is causing emotional distress like any other type of pain.
In today's society, the lack of these laws is highly beneficial, especially to the female gender, because they are the ones doing most of the cheating since your average guy cannot cheat at all. He simply has no other options than his wife or girlfriend and cannot obtain the next one easily. Basically, it only benefits women, the top 20% of males, and nobody else. It is once again another "hidden" benefit that women can use. They can cheat on their husbands and boyfriends and get away freely. What is worse is that society deems this behavior acceptable when a woman does it with sentences like, Yeah, girl, you can do better. He was a loser anyway. Go girl, you are not bound to your boyfriend/husband if he cannot satisfy you enough.
It is a great injustice against a common male and should have been dealt with a long time ago. Actually, men used to have power over the female in case she cheated on him and disrespected him this way, but it used to be in previous centuries.
In today's clown world, men are supposed to just take it and "man up."
