The 'Fury' star is currently in the middle of a messy divorce from his estranged wife Angelina Jolie and the 'Maleficent' actress is said to have been "super aggressive" about the fight for physical custody of their six children.
A source told Entertainment Tonight: "Pitt wants to handle this privately. Whatever is best for the kids, not for him, is what matters. Angelina has been super aggressive. The different things that needed to happen are happening."
Meanwhile, it was previously claimed that the 52-year-old actor - who has Maddox, 15, Pax, 12, Zahara, 11, Shiloh, 10, and twins Vivienne and Knox, eight, with Angelina -has been left "completely devastated" by his divorce.
An insider shared: "He is beside himself and has been crying. He was completely caught off guard and blindsided and had no idea she would do this.
"Angelina filed the court papers a minute before the courts closed on Monday night. He didn't have a lawyer or anything. She had threatened divorce in the past but he did not think she would file this time. He is completely devastated and beside himself. He is a shattered man.
"He's extremely upset. But he is totally focused on just being helpful and making sure his kids are doing as well as possible."
And a source previously claimed that Brad was "committed" to making his marriage work.
They said: "Brad did not want the marriage to end. He was committed to doing what he needed to make it work. He was open to therapy.
"He is emotionally torn. Right now, he is devastated. He still loved Angelina and would have preferred they fight to make the marriage work. He was willing to do whatever it took to save the marriage and didn't know Angelina had already given up on it. He has wanted to protect the children. He didn't want it to play out publicly."
