Firstly, a lot of TV shows and movies you watch it is normalised as though there is an excuse to cheat (I.e. being thrilling to keep a secret, have a better life etc..) But the reality is much different. The person being cheated on probably will suffer for their whole life (anxiety, trust issues, mental health issues, betrayal etc...)
Imagine being in a relationship where you think the person loves you but you are actually being betrayed. I know some people who doubt whether the child is their partners or not due to cheating. I have seen people using work as an excuse to cheating. It is just really sad that people think it is justifiable. There is always a way out leave if you are not happy or sort out your problems. Some people just seem to want to use cheating as an excuse the amount of times I heard "I did it because you didn't show me love." Surely a better way was to leave or try and fix the problem. Nowadays it seems people do not want to try and fix what's wrong with their relationship but play around
