Mandy Moore felt like she was "drowning" during her marriage to Ryan Adams.
Pitchfork said Moore recorded the interview prior to the publication of a New York Times article where she said Adams was emotionally abusive during their relationship.
Moore instead described her co-dependent dynamic with the singer.
"I was living my life for him," the star told host Marc Maron.
"It made me feel worthy," she explained. "It made me feel like I had value, if I could be there for somebody else and serve their needs."
The "This is Us" star said she strove to create a happy family of her own with Adams following her parents' separation.
"I think my co-dependency fed into his co-dependency and some other issues, underlying issues, that it was just, like, the perfect cacophony of madness," Moore said.
"I felt like I was drowning. It was so untenable and unsustainable. I was so lonely. I was so sad. I was lonely with him," she added.
"I knew that this wasn't the rest of my life. I knew that this wasn't the person I was supposed to be with, I knew that I wasn't the person I was meant to be."
Moore and Adams split in January 2015 after nearly six years of marriage.
Moore shared a message of solidarity Feb. 13 on Instagram after calling out Adams for emotional abuse in the New York Times article.
"My heart is with all women who have suffered any sort of trauma or abuse. You are seen and heard. #sisterhoodforever."
