I think cheating is very common. The good side to cheating isn't very bright but sometimes cheating can make you realize what you have, Make you see how good your relationship is. I believe telling someone you cheated on that you cheated one them only makes the cheater feel better. Some people will find out that they don't care for the relationship they are in and cheating makes them realize it and in the end they are happier. I do not believe cheating is nice or necessary in any situation but idk.
