The percentage of people marrying the person they are cheating with is extremely low. For men they generally want their freedom and will often have a mistress, but, in time generally move on. Women are more romantics and may want to stay in the relationship with the person she is cheating with, but, there are some women that play just as hard as men and become 'users and shakers' loving the excitement of 'the chase.' It's magic when one is chasing someone they are attracted too and the possibility of love making is titillating, but once they meet once to several times that relationship may soon get boring too. Cheating is cheap, hurtful and a sign of immaturity. If both parties in the marriage are not happy they should have the guts to communicate this to each other and file for divorce!
