My Mother and Father were married in the temple. My father died and my mother remarried a widower in the temple in a civil ceremony. She dearly loved her second husband and he loved her. He wanted to marry her in the Temple so they would be sealed together for all eternity, but it wasn't allowed since my mom was already sealed to my father. He husband however COULD have more women sealed to him than just his first wife. This is the doctrine of the Church to this present day.
Men will have polygamous marriages in heaven....women will share their husbands with other women.
Interesting comment. How does that square with these scriptures, which talk about marriage in the afterlife?
