“I think she reacted out of love for him. That video is proof of that.”
Married for fourteen years and two kids would also indicate that she was more than simply a gold-digging trophy wife.
I think initially her motive was ‘going for the gold’, but then she grew to love him. That’s not unusual.
Also, I notice that she struck that guy without any regard to her falling down. She ‘took one for the team’, the team being Rupert Murdoch.
