Theron, 39, said she realised her priority has to be Penn, 54, when it struck her that her job was bleeding into her life, reported Aceshowbiz.
“Putting aside that he’s my partner, he’s the love of my life; for the first time, I felt that my work was really bleeding into my life and that made it hard.
“There were moments where I was incredibly unfair to him. And moments where I felt like… He was incredibly unfair to me. But it makes you realise that no matter how complicated it gets, the priority is the relationship,” she said.
