Another point of view whether you are spiritual or not
If both husband and wife have an understanding of the spirituality behind the way marriage is designed and the willingness, that they choose to remain apart of their marriage and they become pregnant they can reconnect through the pregnancy. It allows each of them to see each other in a different light and after the baby is born their bond can become much deeper in the care of their new addition. Again the key word is willingness. If neither are willing to reconcile then a baby cannot aid them in doing so b/c of their unwillingness. Where there is a will there also is a way!
