Trying to find a story.

[RedHot82]

Hi. I am looking for a story I read a few years ago. It was about a man who deals with a cheating wife by taking her to an underground bunker. He keeps her there with the bare minimum at first in term of clothing and amenities. Slowly he treats her better over time and renovates the bunker into a home as they heal the relationship. It was an extreme reaction but couple reconciles in the end story. If anyone can help me it would be greatly appreciated. Thank you
