Re: Second wife.
When you love someone with all your heart and soul, the very best gift to give is the gift of life. So if I had been unable to bless my husband with that gift, I would have wanted another wife for him so that he would be able to procreate. In other circumstances, I think it would have to be like severe famine or disaster where a woman really needed a husband. In those cases, its ok. Any other reason is simply due to the fact that the guy is a pig.
