A Series on Relational Congruence
Leaning Into
Our Nature
Justin M. Eastland, LMSW
You bring up the dishes. Twenty minutes later you are arguing about something else, and neither of you can say how you got there.
Why couples keep having the same fight, and why the fix starts with your own system, not your partner's. Built on the LION Model.
For couples
See the signals, understand the architecture, read your patterns, do the corrective work first.

The Model
Six forces. One framework.
Hover, tap, or focus a pillar
Pressure
The internal and external forces compressing your behavior.
Capacity
Your structural ceiling: the point at which your behavioral system shifts from adaptive to reactive.
Polarity
Directional mismatch in relationships produces the sensation of pushing against something immovable.
Sequence
The behavioral sequences that run automatically in conflict, and the order in which moves are made and received.
Domains
Unaddressed gaps in one area of life quietly eroding the others.
Identity
The core operating assumptions about who you are, which shape the patterns you run automatically.

What Readers Are Saying
Justin doesn't write like a therapist trying to sound relatable. He writes like someone who has actually sat in the room with couples when things fall apart — and figured out what the patterns are. This book gives you the map before you need it.
Justin doesn't give you scripts. He gives you a map of your own system. The LION Model changed how I understand every relationship in my life — not just my marriage.
I've read a lot of self-help. Most of it addresses the surface. This book goes beneath the behavior to the structure that produces it. That's a completely different level of work.
The LION Model reframed how I think about conflict entirely. I've read dozens of books on relationships. This is the first one that gave me a structural explanation for what I was watching happen — not just a prescription for what to do differently.
As a couples counselor I'm always looking for frameworks my clients can actually use between sessions. The LION Model is the most practically applicable system I've encountered.
What sets this apart from other self-help frameworks is that it doesn't ask you to become someone else. It asks you to understand who you already are — and to stop running behavior that contradicts that. That's a more honest starting point than most books are willing to offer.
The chapter on Polarity alone was worth the entire read. I sent it to my partner and we talked about it for a week.
