"They've been together for more than 10 years and always had such a solid marriage," an insider tells Life & Style. "They have three daughters, so it's incredibly sad. He wants to keep the family together, but as far as Mary is concerned, it's over. There's no going back."
Michael, it seems, hadn't split from Mary when he began his alleged fling with the American Idol alum.
"Mary only found out this week about the affair after he confessed everything to her," the source explains. "She had no idea anything had been going on. The last thing she ever thought was that he was seeing another woman."
The duo, who wed in July 2003, have three daughters: Margaret, 9, Rose, 6, and Lillian, 2.
