Amanda Seyfried and Thomas Sadoski reportedly experienced a major shift in their relationship before calling it quits.
Days after the couple confirmed they had separated following nine years of marriage, a source claimed Seyfried's increasingly busy acting career and Sadoski taking on more responsibilities at home contributed to them gradually drifting apart.

Amanda Seyfried and Thomas Sadoski's family dynamic reportedly changed as her acting career became increasingly busy.
According to an insider, Sadoski, 50, began working less as Seyfried's career continued to keep her busy.
"Thomas, for the past few years, was left at home with the kids, so he worked less and less. The dynamic shifted," the source claimed.
The couple shares daughter Nina, 9, and son Thomas, 5, whom they have been raising on their farm in upstate New York.

The source claimed Sadoski's changing role within the family was difficult for the accomplished actor, who has worked extensively in theater, television and film.
"He was isolated," the insider alleged, noting that Sadoski "gave up a lot to be with Amanda."
Meanwhile, Seyfried, 40, reportedly became the family's "worker bee" as her career continued to flourish.
