The Los Angeles Times reported details including games, hammocks and a relaxed atmosphere at the couple's Austin property.
By that point, marriage wasn't the beginning of their commitment.
It was the formalization of a life they had already been building together.
Later that same year, Livingston was born, making them a family of five.
Love During a Career Transformation
The years surrounding their marriage also coincided with one of the most important transformations of McConaughey's professional life.
For much of the 2000s, he had become closely associated with romantic comedies.
They were commercially successful and made him one of the genre's defining leading men, but eventually he wanted something different.
McConaughey began turning away from the comfortable roles audiences expected him to accept.
What followed became known as the "McConaissance."
Films including Mud, Magic Mike, Killer Joe and ultimately Dallas Buyers Club demonstrated a dramatic shift in the kinds of characters he was willing to play.
His performance as Ron Woodroof in Dallas Buyers Club eventually earned him the Academy Award for Best Actor.
Camila was beside him during this transformation.
In a 2017 interview with The Guardian, McConaughey connected his evolving family life with his changing professional priorities, explaining how having his family travel with him helped prevent the emotional separation that an acting career could otherwise create between his work, marriage and fatherhood.
That distinction is important.
A lasting relationship isn't defined solely by romantic declarations.
It is also shaped by logistics, sacrifices and decisions that rarely make glamorous photographs.
Where will the family live?
Whose career takes priority at a particular moment?
How much time apart is acceptable?
How do parents remain present while pursuing demanding careers?
For Matthew and Camila, those questions became part of the architecture of their marriage.
Their Partnership Grew Beyond the Home
Over time, their partnership expanded beyond parenting.
Both became involved in philanthropy, business and public initiatives.
The couple's charitable work has included efforts connected with the just keep livin Foundation, which focuses on programs intended to empower high-school students through fitness, wellness and community involvement.
They have also supported relief efforts and community causes.
Following the 2022 mass shooting at Robb Elementary School in Uvalde, Texas—a tragedy with a particularly personal resonance for McConaughey, who was born in Uvalde—the couple became publicly involved in efforts to support the community and advocate for measures intended to improve school safety.
Their lives have also increasingly overlapped professionally.
They have worked on entrepreneurial projects and, in recent years, have appeared together more openly in business campaigns.
That evolution suggests another stage of a long relationship.
At first, two people build a romance.
Then perhaps a home.
Then a family.
Eventually, if the partnership lasts, their histories begin to overlap in ways neither could have predicted at the beginning.
Keeping a Marriage Alive After the Honeymoon Stage
McConaughey has also been willing to talk about marriage without pretending that lasting love means preserving the emotional intensity of a brand-new relationship forever.
That distinction is significant.
Long-term relationships inevitably change.
Careers evolve. Children arrive. Responsibilities multiply. Bodies age. Families experience victories, disappointments and losses.
The challenge isn't necessarily to keep everything exactly as it felt during the first few months.
It is to continue choosing the relationship as circumstances change.
McConaughey has spoken about the unrealistic expectation that couples should permanently maintain the honeymoon phase. His comments suggest a more practical view of marriage: intimacy must evolve rather than remain frozen in its earliest form.
