Leave out the Christianity for a moment and look at what is going on in the marriage from a redpill lens:
1) Why was he looking at porn if he was married? Why didn't he just have sex with his wife? She had an issue with him looking at porn, but didn't suggest they have sex more.
2) Why is he expected to forego getting a boat in favor of a medical bed. This was a plot point driven by her desires, and no mention was made of applications to medicare, which usually does pay for such things.
