Incest! what an evil you are in yourself. Indeed, curse be to him that gave birth to you
. What happen to this young lady, is not peculiar to her, hence, she should not see life to have come to an end. i would rather advice that if the pregnancy is still at the early stage, secret abortion should be done, or alternatively, the entire family can decide that the child should be born, but should be regarded as a family child. In other words, the paternity/maternity should not be disclose to the child. As for the forth coming marriage, both of them should eschew such an idea, it should rather be imagine than put to practice. On a final note, the girl should not and never blame her fate, God, or life circumstances, rather, i will join hand with her, to blame the parents, who failed woefully in managing the ups and downs of marriage.
I humbly sent my sympathy.
