Marriage Is a Designed Technology
How can you build a marriage that actually works under real pressure? In this book, divorce lawyer James Sexton argues that marriage isn’t a fairy-tale; it’s a technology. It solves certain problems on purpose and creates others by accident. If you treat it like a tool you design, maintain, and periodically upgrade, you’ll make smarter choices before crisis hits and you’ll know how to respond when it does.
Sexton’s core claim is blunt: most marriages fail for two downstream reasons you can address early—you don’t know what you want, and you can’t express what you want. His legal vantage point reveals how small lapses, silences, and avoidable secrets accumulate into affairs, courtroom disasters, and shattered families. He gives you a pragmatic blueprint: design your partnership, speak honestly in real time, protect autonomy while holding the essentials, negotiate sex as part of the deal, control risk factors like social media, and prepare for legal realities just in case.
Why the technology framing helps
When you see marriage as a tool, you stop magical thinking. You ask: what do we want this to do, and what side effects can we accept? You start translating wishes into measurable behaviors—two date nights per month instead of the vague more romance—and you plan for maintenance: renegotiations every year or so, or even a seven-year check that Annmarie suggests. You expect bugs: fading novelty, parenting stress, and money friction. Instead of panicking, you iterate.
Key Principle
Marriage is a technology. Like every technology, it solves certain problems intentionally and creates new problems unintentionally.
Communication as an operating system
Your operating system is how you communicate. Sexton’s Hit Send Now practice asks you to share feelings quickly—via a text or short email—before small slights become calcified resentments. A hurtful dinner joke? Send a short note the next morning. The timing matters: catching the grievance when it’s tiny keeps it solvable. You’re not litigating; you’re reporting a felt state so your partner can respond before it metastasizes.
(Note: Kim Scott’s Radical Candor echoes this—caring personally while challenging directly—yet Sexton’s method is ultra-practical for couples: short, timely, and focused on feelings.)
Design choices you can make now
Treat money, chores, and calendars like product features that need specs. Sexton’s Yours, Mine, and Ours model balances transparency with autonomy through three accounts and clear thresholds for joint decisions. Avoid extreme specialization; swap roles periodically so no one is ignorant or at risk. Shelly found a 65,769-dollar insurance cash-value only after she took a turn with the finances; Cal’s hidden 350,000-dollar Vegas losses show what ignorance costs.
Protect the core while preserving freedom
From Brazilian Jiu-Jitsu, Sexton borrows tight grips and loose arms: hold the essentials—trust, respect, shared goals—firmly, while keeping arms loose around autonomy. Micromanagement and surveillance backfire. Charlotte and Jaclyn shrank their lives to become nothing but spouse and parent; attraction and vitality withered. In contrast, partners who keep separate interests return to the marriage more energized and interesting.
Sex is part of the contract
Sex isn’t a bonus; in monogamy, it’s a core feature. If you can’t talk candidly about desires, you’re left with the stark choice Sexton puts on the table: go without or go elsewhere. Randy’s secret panty fetish, Jess’s shifting kink after kids, Seth’s humiliation in asking for daily sex, and Vacation Jen’s on-trip persona all show how silence breeds secrecy or resentment. Better to negotiate openly, with safety and pacing, than to gamble your marriage on suppression.
Modern accelerants and legal reality
Two real-world accelerants—social media and domestic staffing—multiply risk. Facebook reunites old flames and supplies always-on, curated temptation; Sexton calls it foreplay and quit himself when he felt its pull. Nanny dynamics blend proximity, intimacy, and fantasy; you need explicit boundaries. If things fail, courts are not morality plays. Louie’s win after Gabe botched foundation for a photo of Candy’s injuries shows that outcomes hinge on preparation, not righteousness. Jacob’s refusal to rehearse and a casual remark by Chloe about China expansion became courtroom weapons.
Across the book, Sexton threads a humanist realism: marry the family because you’re marrying their network; accept imperfection in parenting; use intimacy to persuade, not punish; and if divorce comes, treat it as an invitation to reinvent. You can’t guarantee a happy ending, but you can design an honest, resilient partnership—and leave well if it fails.
