Los Angeles, July 30
Actress Julia Roberts\'s 13-year marriage to cinematographer Daniel Moder is reportedly on the rocks as he has \"had enough\" of her.

\"Danny just doesn\'t feel like they have a true partnership. (It\'s always) been (Julia\'s) way or the highway.

\"(She is) very emotional (and can go from) screaming one minute and then apologising the next. (She) goes off on rant after rant, pointing the finger at Danny at every opportunity. (He\'s) had enough,\" a source told OK! Magazine, reports femalefirst.co.uk.

Roberts has had a tough two years after losing her half-sister Nancy and mother Betty.

A source said at the time of Nancy\'s death: \"(She\'s) suffered an emotional collapse. She was already reeling from her mom\'s cancer crisis. Now, she\'s been deeply hurt and stung by all the criticism after Nancy\'s death and feels she doesn\'t deserve it. Julia insists that Nancy\'s death was not a suicide.

\"(She) wants to believe that the overdose was accidental, that somehow Nancy expected to be discovered just before she passed away. Julia\'s been crying her eyes out ever since.\"

Earlier this year, Roberts held a private funeral for her late mother, who passed away after a battle with cancer.
