The reson why some people cheat on their partner

 Spouses cheat because of problems in their relationship - something is missing, passion has faded, partners feel lonely, people find someone who treats them better or who appreciates them more than their current spouse, and so on.Some people love the thrill of sneaking around behind someone's back and doing something without their knowledge. Some people try hard to get caught, and others try to make it last as long as possible. another reason is that They feel like their siginificant other does something wrong to them and then cheat to get revenge on the other person.Cheating situations are never the same, really. Sometimes it ends up with the ultimate happiness of the cheater if they leave their s/o for someone else. Other times it's a drunken mistake that will never be repeated. Usually it's somewhere in between. I was talking to a friend of mine and this is her prospective on cheating ;

 Cheating has nothing to do with your spouse in most cases...it has everything to do with what is lacking inside youself.
It's often about feeling inadequate unless you are getting 'outside' signals that you are OK, sexy, attractive, fascinating, interesting etc. which makes you vulnerable to flattery.....
Sometimes it is about you not having a strong sense of personal integrity, good value system basic honesty.
Sometimes it is like 'notches in your gun'....what image you want to project to your inner circle (excluding your spouse) Sometimes it is due to a sexual addiction.
In my experience, there is absolutely no dissatisfaction with a spouse a home, therefore no motivation to leave.

In my opnion if someone is not pleased with their partner they should leave, instead of playing that person that would be the smart thing to do.
