I think that men who love to stay home, whether they are couch potatoes and just like to stay in the house all day and night and watch TV, or the type who do projects around the house, are the ones least likely to cheat.
I know some men who when not working love to stay at home with their wife and kids. They really enjoy the family life. They start fires in the fireplace and some even like to cook. They enjoy having family around them and have no desire to go out anywhere.
Then there are men who can't stand to stay at home, as soon as they get home from work they washing up, changing clothes, and headed out again. They seem to find many activites away from the home, like bowling leagues, golfing, hunting, hanging out in taverns, belonging to some billards playing group, fishing, or various other activites away from the home. These are the men most likely to cheat on their wives.
Can the same be said about women? And I don't mean women who have to go to work everyday either, they just paying their bills.
I mean the ones who have activities after work.
