The Marriage Maintenance Manuals · Alex Merrett

Stay seriously married.
Whatever season you're in.

A series of practical manuals for long-term couples. One operating system — Monitor, Maintain, Manage, Mend — calibrated for the situation you're actually in: the everyday drift, the year after a betrayal, the neurodivergent marriage. Scripts, checklists, and weekly routines. Not theory.

The System

Four words.
All starting with M.

Every book in the series installs the same operating system for a long marriage. Learn it once, then apply it to whatever season you're in. Each M is a separate skill; each book calibrates the kit for a specific situation.

Research-grounded Secular System-led
M

Monitor

You can't maintain what you don't measure. Track the signals, catch drift early. Most of us drive our marriages without so much as a fuel gauge.

M

Maintain

Daily check-ins. Weekly meetings. Regular rituals of connection and appreciation. The unglamorous work that keeps the engine running.

M

Manage

Conflict is inevitable. Two people sharing a life will disagree. The question is whether you manage conflict, or it manages you.

M

Mend

Sometimes things break despite your best efforts. Mending is the skill of repair: acknowledging harm, taking responsibility, rebuilding what was broken.

The Books

One system. Every situation.

Every volume targets a specific relationship situation. Same tools, same voice, same system, calibrated for where you are right now. Each one stands alone; start with the one that fits your season.

The Standard

Books you can use tonight.

Most relationship books hand you principles and wish you luck. Every book in this series is built to the opposite standard: named protocols with clear instructions, word-for-word scripts for the hard conversations, and a maintenance rhythm you can run without waiting for a crisis. If a chapter doesn't give you something to do, it doesn't ship.

Named protocols Word-for-word scripts Weekly routines Solo-capable Same voice, every book
"The best time to repair the roof is when the sun is shining." The premise the whole series is built on

Author · The Marriage Maintenance Manuals

Alex Merrett writes the Marriage Maintenance Manuals. Practical guides for couples who have read the relationship books, understood the principles, and then watched Monday happen.

She spent over two decades testing what works in her own marriage before turning those tools into a system other couples could use. The result: named protocols with clear instructions, word-for-word scripts for hard conversations, and a maintenance rhythm that keeps a relationship running without waiting for a crisis.

She is a systems thinker. The books are grounded in the research of Gottman, Johnson, Nagoski, and Rosenberg, but they're built for people who need to know what to do, not what to study. Too busy for therapy, too smart to wing it. That's the reader she loves to write for.

Start where you are.

Every book in the series meets a different season of marriage. Go straight to the one that fits yours.
