The primary objective of marriage is for companionship and not child bearing. Although child bearing is also one of the reasons for getting married but should not be seen as a major reason for marriage. Children are blessing from God. Any marriage that have not been blessed with children the both partners should leave happily believing God for a miracle and never see it as a reason for hatred. With or without children, man love and cherish your partner same also to the woman respect your partner
Very correct say children are blessing from most high. But what if this blessing won't come because of some past?
Child bearing for sure is an indelible part of marriage but cannot be the overwhelming reason. It is just painful to know that ur partner can't bear a child or impregnate and he or she knows about it but didn't let you know.
