Alan Ritchson and His Wife Announced Their Split. Read Their Actual Statement.

Twenty years, three sons, and one joint Instagram post. That's how Alan Ritchson and his wife Catherine told the world their marriage was ending — and how they made clear they weren't ending on bad terms.

The "Reacher" star and Catherine Ritchson announced their split on Saturday in a statement posted to both of their accounts, saying they had "decided to end our marriage and continue alongside one another in a different way" after two decades together.

The statement leaned into what the marriage built rather than why it's ending. "Nothing can diminish what these years have meant to us or the love and respect we will always share," the couple wrote, adding that they are raising "three incredible boys who will always be the center of our world." They said they plan to move forward with "friendship, grace and a commitment to becoming the strongest co-parents we can be."

The public split comes after a private and evidently rocky stretch. According to court documents, Ritchson filed for divorce in December, the couple reconciled in March, and then arrived at Saturday's separation announcement months later. Neither has publicly detailed what changed between the filing and the reconciliation, or between the reconciliation and this weekend's statement.

Both Ritchsons say co-parenting their three sons is the priority going forward. Neither has commented further beyond the joint statement, and no additional legal filings have been reported since the December divorce filing. Ritchson, meanwhile, continues to star as Jack Reacher in Amazon's "Reacher," with the show's fourth season in production.
