why do people cheat on their spousesWhy do so many married people cheat on their spouses?

They say they aren't happy with their marriages, so they go out and cheat? Maybe they aren't getting sex at home or they don't wanna be divorced -- but why are there so many people out there cheating?
Because less and less people take God seriously.
A lack of concern.
Self-centeredness
Lack of morals.
Need for attention, affection, stimulation, excitement
Impulsiveness
marriage cant always be handled to be honest,and i think more men cheat than women
Immaturity and cowardice is rampant. It takes a lot of stones to fix a relationship and a lot of stones to leave a relationship. If ever I even feel a slight attraction to another person, it automatically makes me reconwhy do people cheat on their spousessider my own marriage. I generally find that I'm very happy in my marriage and the cheating urge ends right there. Occasionally, I realize that I feel something could be improved, so I set about improving that part of our relationship. I think of it as plugging small holes in a large ship.

Some people set out in a battered dinghy (bad marriage to begin with), and some people just let dozens of holes pop up in their marriage before trying to address any of them. That's usually the kind of person too immature and cowardly to either fix all the holes or abandon ship.
I can't speak for the girls, but for guys there's no p---y like new p---y.
It is the fleshly sin of LUST,why do people cheat on their spouses plain and simple.lust conceives sin.
people are selfish
Because they are unhappy at home. simple. Marriage isn't easy or fun, you know.
Because men often can't divorce or they have to lose half, pay alimony child support and who knows what else. It is just easier sometimes to get a little joy from a side dish. Wrong maybe, easier than a long spendy nasty divorce ya. Women cheat because they get so lonely too. its the same reasons for men and women. You can be in the same house with someone but feel alone
For fat people. Someone would have to be extremely married to even think about getting pussy from some of those fat bitches.
