New blow for Hunter Biden: Ex-wife Kathleen Buhle will release damning memoir in run-up to midterms about breakdown of their 24-year marriage, his affair with Beau's widow and the 'heavy toll' of his sex, drugs and strip club addictions

Hunter Biden's ex-wife Kathleen Buhle will release a memoir in the run-up to the midterm elections about the breakdown of their 24-year marriage, his drug addiction and his affair with Beau's wife that could unearth more embarrassing details about the first family.

People magazine reported Wednesday that Buhle has written a book that will hit bookshelves in June entitled, If We Break: A Memoir of Marriage, Addiction and Healing. 

The book will discuss the 'heavy toll' drug addiction takes on relationships, as Hunter Biden, fueled by a coke and alcohol habit, spent the couple's money on drugs, alcohol, strippers and prostitutes, and engaged in an affair with his dead brother Beau's wife Hallie. 

Buhle accused Hunter of having an affair, being 'emotionally abusive' and using Viagra after she discovered his relationship with his brother's widow, emails obtained by DailyMail.com have shown. 

She tried for years to try help him beat his addiction to crack cocaine and booze, before he found out that he was having a relationship with his sister-in-law Hallie.

The last straw in her marriage with Hunter Biden (left) was when she found out he was having an affair with Hallie Biden (right), the widow of Hunter's late brother Beau 

'When my marriage ended, I felt like I'd lost my sense of who I was,' Buhle told People. 'Anyone who has seen addiction ruin a relationship, or been through infidelity and divorce, can tell you how devastating it feels.' 

Through those 'crushing experiences,' she continued, 'I needed to find a way to stand on my own.'

'Writing this book has been incredibly healing for me,' Buhle told the magazine. 'And my hope is it will be meaningful to those who have been through addiction or divorce, and especially to women who have felt their entire identity was tied to their spouse.' 

'In the end, divorce allowed me to find my strength,' she added.  

The book, Buhle's publisher told People, 'tells her own story from her working class roots on the South Side of Chicago to losing her maiden name and a part of herself in becoming Kathleen Biden, to finding a renewed sense of identity, purpose, and joy after the devastating collapse of her marriage.'   

Buhle and Biden finalized their divorce by April 2017. 

However, six weeks prior, The New York Post reported that Hunter Biden had an ongoing affair with Hallie - with now President Joe Biden only finding out about it when the newspaper's gossip column, Page Six, reached out for comment. 

 Kathleen Buhle's forthcoming book will detail Hunter Biden's extramarital activities, which in divorce documents Buhle said consisted of him spending money on alcohol, drugs, strippers and prostitutes  

Hunter Biden struggled with drug addiction throughout his 24-year marriage with Kathleen Buhle, which ended in divorce in April 2017 

Kathleen Buhle emailed Hunter Biden in July 2016  after reportedly discovering romantic texts between her husband and Hallie - the widow of Hunter's brother Beau. 'I'm leaving you because you are having an affair and you have been emotionally abusive,' she wrote 

Hunter Biden later said in an interview with The New Yorker that he begged his father to send out a statement giving his blessing.  

'I said, "Dad, if people find out, but they think you're not approving of this, it makes it seem wrong. The kids have to know, Dad, that there's nothing wrong with this, and the one person who can tell them that is you,' Hunter Biden said. 

For Buhle, however, the affair was the last straw. 

'I'm leaving you because you are having an affair and you have been emotionally abusive,' Buhle wrote in an email obtained by DailyMail.com to Hunter Biden in July 2016. 'I forgave you for cheating before, I tried to help you get sober and you made it clear, throughout the past year, that you didn't want to be with me. You didn't want my forgiveness and you didn't want my help with your recovery.' 

Buhle called Biden 'cruel' for trying to say it was her fault.  

'You say you were surprised by my asking for a separation and needed time to process it. I was surprised when I found your bottles of Viagra and Cialis. I was surprised when I found airline purchases and jewelry purchases,' the email continued. 

In Hunter Biden's own memoir, Beautiful Things, he said Buhle learned of the affair when she discovered texts between the two lovers.  

A source who talked to The Sun about Hunter Biden's book said Buhle 'tried for years to help him beat his addiction to crack cocaine and booze. But then she found out he was sleeping with his brother's wife. She said he was a sicko.' 

The couple have three daughters together, Naomi, Finnegan and Maisy. 

Hunter Biden also has an out-of-wedlock child with ex-stripper Lunden Roberts.  

After just briefly dating, Hunter Biden married Melissa Cohen in 2019. 

The couple had baby Beau Biden in the spring of 2020. 

By spring 2019, Buhle was dating again, and leaning heavily on her friend, former First Lady Michelle Obama, Page Six reported. 

In a March 2019 text message, Hunter Biden wrote to his father that 'you guys are unreasonably scared of Kathleen.' 

'She's done the worst she can do with no push back,' he added in text messages from his abandoned laptop verified by DailyMail.com.
