Shania Twain is opening up about how she reconciled her painful past.

In this week’s PEOPLE cover story, the country-pop icon looks back on her devastating divorce from producer husband Robert “Mutt” Lange.

The pair’s 14-year marriage 끝났다 ~에 2008, when Twain learned of Lange’s affair with her close friend Marie-Anne Thiébaud.

“It was a very low period in my life,” Twain, 57, 회상.

Following the betrayal, she and Marie-Anne’s husband, former Nestlé exec Frédéric Thiébaud, commiserated over their shared heartbreak and soon after 사랑에 빠지다.

“That is a really strong bond that builds over time, that is rare, that you don’t have in every relationship if you don’t have those deep scars in common,” Twain says of Thiébaud. “We were a big part of each other’s healing.”

After finalizing her divorce in 2010, Twain and Thiébaud, 52, married on New Year’s Day 2011 — a move she wasn’t sure she’d ever make.

“When I got divorced I said, ‘I’m never getting married again.’ I was definitely one of those people that could have written a million songs about, ‘I’m never going to fall in love again,'” Twain says. “But Fred was such an undeniable love.”

The couple are empty-nesters now (her and Lange’s son Eja, also a musician, and Thiébaud’s daughter Johanna are both 21), and they’re now enjoying “a sort of second honeymoon phase,” Twain says. “We’re bonded now in a different way without the kids.”

오늘, Twain is also “in a good place” 그녀의 전과 함께.

“I found peace a long time ago, and maybe peace is forgiveness, 알 잖아?” Twain says of moving on from Lange. “I’m able to have more appreciation for him again, not for what happened in our marriage but for all that he contributed to such a great part of my career and my life. We have a beautiful child from it. The resentment is gone.”

Twain and Lange worked together on three of her diamond-certified albums (The Woman in Me, Come on Over and Up!), and she even still uses his recording studio, though their creative partnership is long over.

“That’s kind of our crossroads area, 이다, 제 생각에는, really appropriate. It feels really good to say that. We share engineers, and so we have this music creative zone that we all go to on our own time,” Twain says.

Twain is preparing to release her next album, Queen of Me — her first in five years and her second she’s created without Lange after their split — on Feb. 3.

“I was coming out of a dark place… now I’m on the other side of that,” 그녀는 말한다.
