The couple announced last week they had split after 10 years of dating, and it has now been claimed they went through a "silent separation" and had been living apart for six months, with even the 'Inglourious Basterds' actress' decision to move from Paris to New York unable to save their failing relationship.

A source told the new issue Grazia magazine: "Diane is fiercely independent and ended up resenting leaving Paris to be with Joshua. She's also disillusioned with Hollywood and wasn't interested in attending events as part of a power couple, she needs her own space. The move was make or break and i the end, it broke them. Joshua is heartbroken."

Diane, 40, previously described moving to New York while 38-year-old Joshua was appearing in off-Broadway play 'Smart People' - as a "big step into adulthood".

Asked if she would consider marrying again, the blonde beauty - who was previously wed to director Guillaume Canet for five years - said: "Welcome to my dilemma. I just moved to New York. I need to unpack and buy some house stuff, like candles and books.

"[Moving here] was a major commitment. That's a big step into adulthood for me, to allow that time for someone else out of my time."

Despite ending their relationship, the former couple have vowed to stay friends.

Their representatives said in a statement: "Diane Kruger and Josh Jackson have decided to separate and remain friends."

And the source added: "They had their fair share of issues but fully intend to stay friends."
