Who's to say she didn't enjoy making breakfast and tending to his children? If she didn't, why would she have quit her job to spend more time with Jonah and his kids? Find another boyfriend who made $6.5 million dollars last year, owned a mansion in AZ and yet another mansion in San Diego? What are the odds? Slim to none. I think it was the money that was the motivating factor in the relationship, at least in the beginning and it is a pretty attractive bonus. Kids are there part time, and when they weren't it was probably non-stop luxury.... fancy dinners, nicer clothes than she ever dreamed of, nice cars, probably fantasy vacations... She was playing house with a billionaire and now it was over. MOO.
If she were running in those circles while she was dating JS the odds might have been pretty good, IMO. She was a very attractive woman. And since she did it once (found a millionaire boyfriend), who is to say she couldn't have done it again? Even LE implies her life wasn't all roses. Why would she be so devastated to lose that?
