I found out yesterday that my best friend cheated on her boyfriend the other day, with a guy who also has a girlfriend. Which she then said how she is not going to tell her boyfriend as he will never find out about it and her reasoning was that this guy was "really good looking". I personally think cheating is wrong, and can never see me doing this to my boyfriend. But this made me realise most of the relationships I know, someone in that relationship has cheated on the other.
I was wondering why is it that people even cheat on their partners? not like there's a specific answer, and will vary for each person, but I honestly don't understand the reasons why, as I think if someone wants to be with more than one person by cheating, they shouldn't be in the relationship in the first place. Then in relationships like the one I mentioned above, she cheated but it's still going to stay with him and not tell him what happened?
