In 2024, Statistics South Africa recorded 24,202 divorces. Women filed 57.3% of the proceedings. The median marriage lasted between eight and eleven years. Fewer than 12% of engaged couples had any form of pre-marital counselling.
We didn't write this book because we have all the answers. We wrote it because we counted the cost of pretending the conversations don't matter.
The conversation that started everything
In April 2026, four months after we started our partnership, Portia asked Isaac one question over an ordinary Mpumalanga afternoon:
"Are you really sure? Walk me through your thought process."
She wasn't asking whether he loved her. She already knew that. She was asking him to do something harder — to go inward in real time, to consult his own mind in the present moment, and produce the most honest answer it held.
Isaac's answer that day became the foundation of everything we've built since:
"We are living in the latest moment ever. Every moment before this one has been a building moment — building to today, to this question, and to the way I am answering it right now."
And our shared diagnostic for every imperfect situation that has followed: "What is this teaching us?"
The whole book in one sentence
If two people both have a growth mindset, there is almost no problem they cannot solve together. If even one person lacks it, there is almost no problem they can.
That's the thesis. Everything else in the book is explanation, evidence, application, and — yes — comedy.
What's inside
Grow Together or Grow Apart is an A5 paperback we wrote from Secunda, Mpumalanga, and it does not contain vague romantic advice. It contains:
- The Golf Course Problem — why we expect to love perfectly on our first swing when nobody expects to play golf perfectly on theirs
- The Most Dangerous Sentence in a Relationship and how to dismantle it
- The Five Pillars — Conflict as Collaboration, Transparent Communication, Financial Partnership, Vision Alignment, and Emotional Safety (the Three A's from Sue Johnson's EFT)
- John Gottman's Four Horsemen — Contempt, Criticism, Defensiveness, Stonewalling — and a growth-mindset antidote for each
- The Growth Mindset Relationship Assessment — score yourself 1 to 5 across Self-Awareness, Relational Adaptability, Emotional Regulation, and Shared Vision
- Five 90-second short film scripts written for your phone and your lounge, not a studio
- The Comedy Section — stage scripts for when laughter is the teaching
- The full Couples Toolkit — Growth Mindset Assessment, Partner Comparison Table, Conversation Questions, Our Relationship Contract, Emotional Safety Pledge
The book is written to be written in. Fill the pages. Make it yours.
The research underneath
Every framework in the manual stands on five research foundations: Carol Dweck's mindset psychology (Stanford, 2006), Knee, Canevello, Bush & Cook's Journal of Personality and Social Psychology paper on growth-believing couples (2008), John Gottman's 40-year longitudinal research at the University of Washington (3,000+ couples, 93% predictive accuracy), Sue Johnson's Emotionally Focused Therapy (70–75% clinical success rate), and Statistics South Africa's 2024 divorce data.
We argue with the research where lived experience pushes back. We cite it where the evidence has held.
Who this book is for
"This book is not for people looking for relationship advice. It is for people who refuse to settle for an average relationship — and are willing to do what most couples will not."
It's for couples who already suspect that the conversations they avoid are the conversations that would save them. It's for the partner mid-panic because their other half just asked a very serious question. It's for the couple who came to the golf course having never held a club, missed the swing, and want to learn how to practise instead of declaring the game broken.
