You get only what is in your destiny, why hurt someone inorder to have a child?
I truly believe this, b/c I have a cousin who was married for over a decade, and his wife could not have kids (that's what everyone thought).....after numerous ways of trying to have a baby....they gave up.
And one day she just got pregnant on her own.
It was least expected, especially as my cousin said he had given up and had resigned to being childless, and even when he had given up praying for one. (They had gone to gurdwaras, temples to pray; anywhere someone said would bring them luck etc.)
And now they have been married for 15 years, and have a son and daughter.
I think anything is possible, as God has the ability to change your life whenever.
There is no need for a second wife, as my cousin was told by some males do that, and he said he loves his wife MORE than the unborn child who may bring him misery.
