Why do really other people cheat?

i have no idea!!! i wish i know so we can prevent our man to go and find someone else. people when asked, if they have cheated and said yes.. the common answer to whys i hear is that they felt the other woman has shown they are loved more than the gf or the wife... so maybe that is where it is steming from...?

People cheat not because they want to but because they have to. Not to hurt someone's feelings but to let him/her realize him/her mistakes that pushes you to do such thing.

I think that sometimes people have an intellectual idea of what a relationship should be and when it isn't that way in actuality, they cheat. In addition, I think that some people simply aren't monogamus. I think that the Cheater has to feel guilt about his or her cheating because he or she knows that it isn't right. I think that they continue to cheat because they really want to get caught.

What I think is, people cheat because they are looking for something that they can't find from their partners. I know that some would say that we should stay contented with what we already have, but sometimes, when there are deeper problems in between, falling in love with another person in inevitable.
