I personally adhere to the doctrine that mutual understanding and trust always spark off relationship whether a marriage or live in. If a girl and a boy are incestuous and marry later. It means they are loyal and courteous and bind in a relationship with mutul consent. if jilted due to personal or other and decides to follow there own path with different companion.They have understood that their relationship will not work for longer period of time and voluntarily set apart.Relationships are always circumstantial and happens by chance.iN our society there are two ilk of group of people, who always impugn on each other's point of views, one who follows and other who abhor it. If you ask married guy he will say no to live in and vice versa.Cultural, economical,enviromental and informative transitions have caused live in relationships.Live in relationship is mushrooming in Metros where people from other cities come for education,job or livelyhood and parental control almost become nix there,so they adopt which is easily available due to insecurity or emotional front.So the choice are theirs and lives are theirs.SO only couple knows they follow the life of debauch or life of moraly correct
