There are factors that MIGHT not have been considered in all of our speculation re. the PERSONAL lives here.
Elin is Swedish- perhaps she is far more liberal re. sex than most American women would be?
Perhaps she knew all along he was cheating and they have an
‘open’ marriage that was just fine as long as nothing made the press about his other women?
This may be a case of extreme embarrassment about things going public more than personal pain.
Look at the British royal family- the Diana/Charles thing in particular. EVERYONE knew he had horsefaced Camilla on the side even as he planned a big wedding. Mistresses were to be accepted and ignored by the wife. Faithfullness is not an expectation when you’re rich and titled- discretion is, however.
Might be the same case here. In Sweden such a marriage might be commonplace and cause no moral scandal whatever.
I think you're right. European society is far more casual about adulterous behavior. Sounds like a good move.
Memo to Tiger: just don't move in next door to Jesper Parnevik.
