A source tells ET, "As far as Jim was concerned, Cat was separated from her husband. She was planning on starting divorce proceedings in December. He would never have been out publicly with her if she was still with her husband and still married."
White was found dead of an apparent suicide in her home on Monday, Sept. 28. Several notes were found at the scene, including one addressed to Carrey, whom White dated on and off for three years. The couple was most recently spotted on a romantic dinner date on Sept. 19.
