The part that I can't reconcile is that she is clearly tough enough to play with the big boys, as evidenced by her willingness to take Kurtley on and possibly as reported tell Kurtley his future is down the toilet. But then appears to turn tail and bail on the tour.
It could simply be a case of after the adrenaline has cleared she lost her desire to fight the good fight, but someone of her youngish age to have risen to the top in her chosen field in a male dominated industry would be unlikely to suddenly lose her nerve in my estimation.
The only thing that makes sense to me is KB (Kurtley Beale) said something particularly nasty, that is also true. It's not the lies that get to people, they can be ignored. It's the truth that hurts the most.
