Um... if she’s at home and he’s gone, how is that “intentional absence” on her part?
Does she have to stay home alone? Is there any reason, any reason at all - that she couldn’t have met him on the weekends? Tiger wasn’t stuck in a dump, he stays at luxury resorts, and the locations are hardly inhospitable. Why didn’t she join him? My wife would, she would insist on accompanying me - because she loves the adventure, and we love doing things together.
It’s like tempting a recovered alcoholic with a drink. He may have been the playboy before he was married, and left alone for extended periods of time - with ample temptation, the result was almost inevitable.
