"Reports claim that Jim got fed up with Jenny's ongoing cajoling of him to help her career," Lieberman said. "But Jim has a history of being a commitment-phobe, so it could well be that he was just feeling smothered after so many years in the same relationship."
Perry said that the spilt may have more to do with McCarthy's priorities -- her son and her efforts to increase awareness about childhood autism.
"They were a wonderful duo," Perry said. "It sounds like this is a case of two big personalities that have priorities of their own going in opposite directions. Also, there have been rumors that Jim has been battling depression. McCarthy already has a son with special needs, and it sounds like she doesn't have the time to focus on him and his significant amount of needy attention."
