The painful events likely refer to his high-profile divorce from Jolie after she accused Pitt of being verbally and physically abusive towards their children, prompting an investigation by the FBI and Child Protective Services.
Both bodies cleared him of wrongdoing and Pitt has consistently denied any abusive behavior, but his children continue to pull away from the Troy actor as they grow up and make their own decisions on life.
Additionally, there were claims of substance abuse, which Pitt later acknowledged, admitting to struggles with alcohol and the actor has sought to focus on his personal growth and professional career amidst these challenges.
