Join the Twenty-Three.
Less than 25% of marriages remain happy over the long term.
Those who stay happy don’t rely on luck. They intentionally keep the fire alive.
DUO is on a journey to make more marriages happy by providing the best frameworks, daily tools, and faith-based wisdom in one simple system. Start together, or take the first step on your own.
Out of 100 couples who married 15 years ago, nearly three-quarters eventually lose the very connection they promised to keep. But a final group—The Twenty-Three—finds a way to stay genuinely happy.
77%
Drift
settle, survive or leave
23%
Stay
built it on purpose
Thriving marriages are not random.
The couples who stay genuinely happy long-term practice patterns most couples were never taught.
DUO makes those patterns visible.

40%
The Divorced
A slow buildup of disappointments, distance, and resentment.
Understanding what breaks marriages is the first step. Start with Foundations.
“The hope here is not simply that you avoid becoming part of the 40% who leave. The hope is that you join the Twenty-Three. There is very little enjoyment in the middle.”
