Normally, husband and wife are two different individuals who live together with the relation of man and women , children will have the blood relation of mother and father so they are more connected to mother and father. Its difficult to reconcile between a man and woman after the bitter incidents, but blood relations don't require any, one cry or one sorry is enough. That the relations of marriage and marriage related relations. Thats why daughter and daughter in law is different. You can hate you spouse but cannot hate your child.My view on Dev and Sona - even though Sona and Dev have reconciled, the wounds are left on their scar, its difficult to heal, thats why Dev told that he his hesistant to hold her hand while he was in the car.Sorry, if I have bored by writing this.
