I was recently married to my husband in the Twin Falls, Idaho temple for time and all eternity.
In her obviously orthodox Mormon paradigm dad's a bishop, she went to BYU and on a missionunderstand that she believes her husband must be an orthodox Mormon and get married to her in the temple. It's not fair to put words in her mouth and thoughts in her brain like this.

It is very difficult being a Doctors wife.
