Quoting an unnamed source "close to Nordegren," People Magazine reported the golfer's wife "wants to stay away from Augusta and not get involved in the frenzy of the Masters."
The magazine quoted the source as saying Nordegren's marriage to Woods has become a matter of "going through the motions of family life" and "a charade" for the sake of their children in the wake of the golfer's admission of numerous extramarital affairs.
"She suffered through the pain of her parents divorcing and doesn't want to do that to her kids," the source said. "But she is not happy in the marriage. The trust is gone."
By not attending next month's Masters event, Nordegren wants to send a message that she is continuing to live with Woods at their Windermere, Fla., home "only because of the children. They come first."
Woods said Sunday in interviews broadcast by ESPN and The Golf Channel that he lived "a life of a lie."
"You start coming to the truth of who you really are, and that can be very ugly," he said.
