After two decades of marriage, Alan Ritchson and his wife Catherine have announced that they are going their separate ways.

The Reacher star, 43, and Catherine shared the news in a joint Instagram statement on September 12, 2026, revealing that they had “decided to end our marriage” while making it clear that their relationship as parents — and their commitment to their three sons — remains at the center of what comes next.

For a couple whose story stretched from their teenage years into adulthood, marriage and parenthood, the announcement carried a noticeably reflective tone.

“After twenty years together, Cat and I have decided to end our marriage and continue alongside one another in a different way,” they wrote.

It was not framed as a bitter public breakup. Instead, Alan and Catherine looked back on the extraordinary amount of life they had shared.

“We grew up together. We built a life and a family together,” their statement continued. “And we are raising three incredible boys who will always be the center of our world.”

Those sons — Calem, Edan and Amory — are now the couple’s primary focus as they transition from husband and wife to co-parents.

Alan and Catherine emphasized that ending their marriage does not erase what came before it. They said that “nothing can diminish” the years they spent together or the love and respect they will continue to share.

Perhaps the most revealing part of the statement was their description of what they believe their family needs now.

“The best gift we can give one another — and our boys — right now is friendship, grace and a commitment to becoming the strongest co-parents we can be,” they wrote.

They also said they wanted to give each other “room to grow into the people we are becoming.”

It was an unusually measured message for the end of such a long celebrity marriage — especially because Alan and Catherine’s relationship began long before Hollywood fame became part of their lives.

The two first met while attending high school.

Their paths later crossed again when Catherine was studying at the University of Florida and Alan traveled to Miami for a modeling job. That reconnection eventually developed into a relationship, and the pair married on May 12, 2006.

Over the next 20 years, they built a family while Alan’s career steadily expanded.

Before becoming widely known as the towering title character in Prime Video’s Reacher, Ritchson worked as a model and appeared on American Idol. He went on to play Aquaman on Smallville, starred as Thad Castle in Blue Mountain State and appeared in projects including The Hunger Games: Catching Fire and Teenage Mutant Ninja Turtles.

But even as his public profile grew, his marriage to Catherine largely remained outside the constant cycle of celebrity relationship headlines.

The couple occasionally appeared together at premieres and industry events, and Catherine publicly supported Alan’s career. When Season 3 of Reacher premiered in 2025, for example, she enthusiastically celebrated the show and wrote that she was “SO PROUD.”

Alan had been equally public about his appreciation for his wife.

On their 19th wedding anniversary in May 2025, he shared a video tribute featuring moments from their marriage and family life.

“I’m the luckiest man alive,” he wrote at the time, describing building their marriage and family as the greatest privilege and success of his life.

He praised Catherine as a source of wisdom, strength, joy, adventure and love, adding that he and their sons felt deeply fortunate to share their lives with her.

In retrospect, those words make the couple’s announcement just over a year later feel especially poignant.

PEOPLE noted that Alan did not post a similar tribute for their 20th wedding anniversary in May 2026. However, that absence alone does not explain what led to their separation, and the couple has not publicly detailed the private reasons behind their decision.

Their family had also continued making public appearances together. As recently as July 13, 2026, Alan and Catherine attended the New York premiere of Motor City with all three of their sons.

But according to a report cited by PEOPLE, their marital difficulties may have stretched back further.

TMZ, citing legal documents, reported that Alan had actually filed for divorce in December before the couple reconciled in March. Months later, they ultimately announced that their marriage was ending. PEOPLE said it reached out to Alan’s representatives for additional comment but had not received an immediate response.

Whatever happened privately during that period, Alan and Catherine are asking the public not to speculate too aggressively.

Their Instagram post had comments restricted, and the couple directly addressed the intense attention that can accompany the breakup of a famous marriage.

“Change is hard enough without the whole world weighing in,” they wrote.

They asked for privacy and compassion, particularly because their sons are involved.

“We hope, especially for the sake of our boys, that you will allow our family to move through this chapter with privacy and compassion,” their statement said.

They concluded by thanking supporters and promising to continue prioritizing the “health and happiness” of their family.

For fans accustomed to seeing celebrity separations unfold through accusations, competing statements and public legal battles, Alan and Catherine’s announcement stands out for its emphasis on continuity rather than conflict.

Their marriage is ending, but both appear determined to preserve the family relationships built during those 20 years.

That does not necessarily make the transition easy.

When two people have known each other since adolescence, built a home together, raised children and navigated the changes that come with one partner becoming internationally famous, separation can mean much more than simply ending a romantic relationship.

It can require redefining an entire shared life.

And that is essentially how Alan and Catherine have described what they are attempting to do.

They are no longer continuing as husband and wife, but they are still connected through the sons they are raising and the history they created together.

Their own words perhaps best capture the complicated nature of that transition: they intend to “continue alongside one another in a different way.”

After 20 years of marriage, that different way is only beginning.

For now, neither Alan nor Catherine has publicly offered a detailed explanation for why their relationship reached its end.

Instead, they have chosen to focus on what they hope will remain: friendship, respect, family and a commitment to raising their children together.

It is a quieter ending than many celebrity marriages receive.

But for a couple who says they essentially grew up together, their announcement suggests that the end of the marriage does not necessarily mean the end of the bond they spent decades building.
