This is one of the situations that one of my main characters have to contend with. It was not an intent on presenting a political or religious opinion, it only contributed to the plot.
There is a lot of conservative push for certain laws such as this that sparked my imagination and wondered, what could happen if society decided to go in this direction. So a future America where if you are married, you are stuck till death.
That is what one of the main characters have to deal with without the spouse realizing what they had been turned into. It really turned out well I think as the entire family was affected not only by the changes that two family members were going through but also the disaffection that lead to an attempt to get out of the marriage via death.
