The actress, who was recently nominated for an Oscar for her performance in 'Changeling', is stressed out according to Entertainmentwise, and needs to relax by herself away from her six kids and husband. A source said: “Angelina has told Brad she needs her space.

She is a fiercely independent person and needs time alone to feel sane and happy. Her tendency is to bolt. When she is feeling stressed and overwhelmed she often goes away by herself."

This has apparently led to marital strife, the source added: “There is a massive tension between her and Brad and they have been fighting."
