We’re kicking off our new season this Valentine’s Day with a story from a Modern Love veteran.David Finch has written three Modern Love essays about how hard he has worked to be a good husband to his beloved wife, Kristen. As a man with autism who married a neurotypical woman, he found it especially challenging to navigate being a partner and father. To make things easier, Dave kept a running list of “best practices” to cover every situation that might come up in daily life. His method worked so well that he became a best-selling author and speaker on the topic.But almost 11 years into their marriage Kristen suddenly told him she wanted to be "unmarried." Dave felt blindsided. He didn’t know what that meant, or if he could do it. But Dave wasn’t going to lose Kristen, so he had to give it a try.Valentine’s Day Bonus: How does politics affect your love life?
