We don’t know the answer to these questions, but they are not the issue.
So, we just ignore any contributing factors? Doesn't matter what Elin did, or refused to do - no matter what she was like in private, no matter how she refused to travel with her husband - Tiger is totally and utterly at fault? Golly, I thought marriage was supposed to be a TEAM effort; I guess a husband is just a slave to whatever his wife condescends to tolerate. My mistake.
