• Hunter Biden's ex-wife Kathleen Buhle addressed their split in a recent interview while promoting her book
  • Buhle said she lost her sense of being her own person when her marriage with Biden ended
  • Buhle added that the crushing experience also made her realize she needed to stand on her own

Hunter Biden's ex-wife Kathleen Buhle got candid about what happened in their marriage.

Biden, 51, and Buhle, 53, were married from 1993 to 2017. They split after 24 years of marriage. They have three daughters, Naomi, 28, Finnegan, 22, and Maisy, 21. For the first time since their split four years ago, Buhle opened up about their marital crisis while promoting her upcoming memoir, "If We Break: A Memoir of Marriage, Addiction and Healing," which her publisher called "a story of resilience and self-discovery."

"When my marriage ended, I felt like I'd lost my sense of who I was," Buhle, a nonprofit development executive, told People. "Anyone who has seen addiction ruin a relationship, or been through infidelity and divorce, can tell you how devastating it feels. But what I also realized through those crushing experiences is that I needed to find a way to stand on my own."

According to her, writing the book was an "incredibly healing" experience. "My hope is it will be meaningful to those who have been through addiction or divorce, and especially to women who have felt like their entire identity was tied to their spouse. In the end, divorce allowed me to find my strength," she added.

Following their split in February 2017, Buhle alleged in a legal filing that her estranged husband spent money on drugs, alcohol, prostitutes and strip clubs.

Biden admitted his addiction struggles in his memoir "Beautiful Things," released in 2021. Hunter shared how his brother Beau's death affected him.

"After Beau died, I never felt more alone. I lost hope," he wrote, per ABC News.

He recalled the time when he cycled through addiction, rehab and sobriety while keeping his family and career as a lawyer. His family tried to help him with his mom, Jill Biden, inviting him to a family dinner in Delaware.

However, at the time, he sensed that his parents had another agenda than sharing a meal with him after finding his three daughters and two counselors from a Pennsylvania rehab center where he had been a patient on the table upon his arrival.

He swore at his dad, President Joe Biden, and bolted from the house. The POTUS chased him down the driveway, "grabbed me, swung me around, and hugged me. He held me tight in the dark and cried for the longest time. Everybody was outside now."

"For the next two days, while everybody who’d been at my parents’ house thought I was safe and sound at the center, I sat in my room and smoked the crack I’d tucked away in my traveling bag," he continued. "I then boarded a plane for California and ran and ran and ran. Until I met Melissa."

Biden credited his sobriety to his second wife, Melissa Cohen, and the love of his father and late brother. Biden and Cohen share 1-year-old Beau Biden Jr.

Buhle's book, "If We Break," will be released on June 14.
