Great description of the boredom and predictability that can occur in marriage. I really liked the teaser opening, long set up, and then the subtle pay off. That last sentence wound up too long, and it’s a ‘comma splice’ (no conjunction between your two subject/verb pairs, if I’m reading it right). I know it seems like nit-picky grammar, but it does make for a more difficult read.

The run on was intentional — it was supposed to work as color on the quality of the conversation. I can see how it might not work, but I’m not sure how to fix it.
