The star previously opened up about his "pain" amid his split from his ex-wife Amber Heard, which ended with a lengthy court case. The Pirates of the Caribbean star met the Aquaman actress on the set of The Rum Diaries in 2009 and they started dating in 2012. The former couple tied the knot at their LA home on 3 February 2015, but they got divorced in August 2016.
Amber received $7 million in the settlement and the pair released a joint statement describing their relationship as "intensely passionate and at times volatile."
Days before Amber filed for divorce in May 2016, Johnny had suffered another heartbreaking blow – his mother Betty Sue died from cancer.
"I was as low as I believe I could have gotten," he told Rolling Stone as he recalled the difficult time in his life, both emotionally and financially. "The next step was, ‘You’re going to arrive somewhere with your eyes open and you’re going to leave there with your eyes closed.’ I couldn’t take the pain every day."
Speaking about writing a memoir while on tour with the Hollywood Vampires, he added: "I poured myself a vodka in the morning and started writing until the tears filled my eyes and I couldn’t see the page anymore.
"I kept trying to figure out what I’d done to deserve this. I’d tried being kind to everyone, helping everyone, being truthful to everyone. The truth is most important to me. And all this still happened."
Johnny's mother was diagnosed with cancer in 2013, but after she passed away in 2016, he described her as "maybe the meanest human being I have ever met in my life."
However, he said during a court appearance that her death "opened my eyes quite a lot to a number of things," and prompted him to raise the subject of divorce with Amber.
Speaking about his childhood, in which he claimed his mother give him "irrational beatings", he told the Fairfax County Courthouse: "I forgave her for all that, as one would – should.
"It opened my eyes to the fact that – yes, try, in relationships, whether friendships, whether courtships, whether marriage. Try your best. If it’s not going to work, it’s not going to work."
He called Amber to discuss the end of their marriage. "I very calmly said, look, I’ve made a decision and I think it’s the best thing. I’m going to file for divorce. But I’m not going to cite irreconcilable differences. I’m not going to cite any violence. I’m going to state this: we simply, the two of us, we simply don’t want to feel as though we have a collar around each other’s neck and a leash attached to it, and then this piece of paper that proves that that’s true," he said.
Following their divorce, Johnny and Amber's relationship soured and they have been involved in several lawsuits since.
