Sometimes two people that get married find they are not compatible with each other and fall out of love and if the man has an affair he may fall in love with the other woman and although cheating is not the right thing to do if he left his wife he does not love for the other woman then he made the right choice. If he still loves his wife then he has hurt her deeply by cheating with another woman and he could well have lost a wonderful and loving person over an affair. Often the other person in the affair is not all the married man thinks they are and he will be the one to pay the price.
