In psychiatric studies the men do cheat more on their wives. Women will stay in a marriage even if it is not a happy one because they take their vows and duties more seriously, especially promises to God, for better or worse. To alot of men it is all about sex and they will come back to their wives, as the mother of their children, and possibly their childhood sweetheart, or first love. Yes, Women do cheat but it is usually because they are beaten, rejected, or treated so badly that they are seeking a man who will show respect and kindness to them, or someone who they find mutual things in common with after their children have left home. These studies come from many women with different ethnic backgrounds too. It is very interesting to be a detective and investigate these extra maritial affairs, sometimes you just want to shoot the perpetraitors for their sleeziness!
