Amanda Seyfried and Thomas Sadoski have separated after nine years of marriage, but sources close to the actress say the split followed a gradual breakdown rather than one dramatic event.
The biggest strain was reportedly the imbalance created as the actress’s career accelerated while Sadoski spent more time at home raising their two children.
Insiders describe a relationship that slowly shifted from marriage to friendship as work and parenting responsibilities pulled Amanda Seyfried and Thomas Sadoski in separate directions.

A source close to Seyfried told the Daily Mail that the actress and her husband had been apart for at least six months and characterized the end of their marriage as a “gradual decline.”
Despite the split, the duo is said to have “kept things very civil” and have “been geniuses about co-parenting” their kids: Nina, 9, and Thomas Jr., 5.
“They have not been on a red carpet much together since 2024,” the source noted. “She has preferred to go out alone, and she has also been heading out on girls’ trips with her female friends in recent months.”
“Fans should have gotten a heads up when she listed her Hollywood Hills home last month for $3.2 million,” they added.
Seyfried and Sadoski announced the end of their nine-year marriage in a statement shared with People Magazine.
“We have been separated for a while, and it’s proven to be the right move for us and our family unit,” the ex-couple said. “We’ve got each other forever—and it’s GOOD.”
The Actress’s ‘Insecurity’ About Her Career Reportedly Affected Their Marriage

The most detailed explanation from the insider centers on Seyfried’s demanding career.
She spent the past several years taking on a heavy run of film and television work, including “The Dropout,” “Long Bright River,” “The Housemaid” and “The Testament of Ann Lee.”
“It got weird between them because she has been working a lot,” the source said, noting that she felt she needed to take as many projects as possible before turning 40 because she feared major roles “would dry up.”
“But she is so well liked in Hollywood that work just keeps coming for her, so I’m not sure why she was worried so much. She is so talented, she doesn’t need to worry about losing work,” the source continued.
They noted that while Seyfried is deeply dedicated to her work, “there is always that insecurity with her – like she is always trying to prove herself. There is a nervousness that is palpable.”

As Seyfried’s workload expanded, Sadoski reportedly increasingly handled their personal lives, with the Daily Mail’s source noting that he “was left at home with the kids, so he worked less and less. The dynamic shifted.”
The insider described Seyfried as the “worker bee” while Sadoski was left with their young children on the family’s farm in upstate New York. That imbalance was presented as a central reason the relationship changed.
The source also linked the strain to Seyfried’s ambition. “She wants to win an Oscar,” they noted, pointing to her Emmy and Golden Globe recognition and her desire to keep advancing professionally.
The actress was reportedly upset when “The Testament of Ann Lee” failed to bring the Oscar recognition she had expected.
“Amanda thought she was going to get an Oscar nomination for ‘The Testament of Ann Lee’ last year, but she didn’t, and when that failed, she was very upset,” the source claimed.
Thomas Sadoski ‘Gave Up A Lot’ To Be With The Actress

Sadoski was not portrayed as unwilling to contribute at home, as the news outlet reports that he sacrificed significant parts of his professional life to support Seyfried and their family.
“He is a very good actor and respected in the theater world and in TV; he had a big career. He has a Tony. He really gave up a lot to be with Amanda,” the insider said. “He was isolated. It’s not the best feeling for a man.”
As Seyfried’s schedule grew busier, Sadoski became the more available parent, a role that reportedly left him isolated from the professional world he had built.
Seyfried had previously acknowledged that Sadoski made sacrifices for her. In a January 2026 Vogue interview, she said he “sacrifices a lot for me” while explaining that the opportunities coming her way were unusually significant.

Seyfried and Sadoski’s split was not entirely blamed on either party. One insider described the situation as an imbalance that can develop when an actress tries to maintain a major career while raising young children.
“It’s very hard for actresses to have kids and balance family life with a big career, so people should empathize with her,” the source told the Daily Mail.
Seyfried and Sadoski met in 2015 while working on the Off-Broadway play “The Way We Get By,” reunited on “The Last Word” later that year, and began dating in 2016.
They married in March 2017 and welcomed Nina shortly afterward. Their son arrived in 2020.
The relationship that began due to their acting careers eventually became shaped by the same career pressures that pulled them apart.
According to the source, Seyfried was increasingly focused on work while Sadoski was increasingly focused on home.
“For the past year they have been more friends than lovers,” the source said. “They have drifted apart, but the friendship is still there. They will always be close because of the children.”
