I have a very close friend. He does not hide anything to me. My friend is a married person. He has a girlfriend. His girlfriend also married.They share each others sorrows and happiness. They also take advice from each other when they are in troubles. There friendship is only friendship.Nothing more than that.But both of them did not tell about their relationship to their spouses. Are they deceiving their spouses? I don't think so. Do you?
