Have you ever watched their body language when the couple is in front of the camera during the interview process?
They rarely touch or look at each other.
Kate always has her legs crossed, and turned away from Jon.
She keeps her arms in front of her stretched out in a defensive mode.
Plus, it's obvious that everything has to be her way.
There's no bending or compromising with her.
I honestly can't blame him for wanting a divorce from her.
