Do you think most people have extramarital affairs by accident or intentionally?

i think people who have extramarital affairs are very unhappy with their marriages but instead of addressing the problems that they have in their marriage, they go out and start an affair (the easy way out). others (who don’t have extramarital affairs) have the courage and the will to solve the problems in the marriage. every marriage has some problems by the way. i’ve never met a single couple who never had any problems or arguments at all.
i think one should try to stay in touch with their spouses “real” feelings and know when he or she is unhappy. however, sometimes we fail to catch those signals and have to face the ugly consequences of a cheating spouse. its really painful.
i think its always intentional and due to selfish reasons. the spouse who cheats chose to take the easy way and the fun way out. its never innocent. every sensible adult knows what they are getting into when they agree to going out for dinner with that guy or gal they cheat with or when they talk to him or her on the phone and hide it from their spouse. when ur having to keep it a secret from your spouse, therez definite trouble in your marriage.
