After filing for divorce from Schwarzenegger, Shriver sought “to be in silence and look for advice” at a convent, she revealed during an appearance on the Making Space with Hoda Kotb podcast.

I was like, ‘Who is that?’ “

The mom of four added that she often felt disconnected from herself in her marriage, as she felt overlooked when Schwarzenegger or her famous family members were in the room.

“I would find myself getting angry at people who came up and didn’t acknowledge that I existed when I was standing next to Arnold, or when I was standing next to my uncle or somebody,” she said.

“And then I [realized] they were teaching me a lesson that it’s not about whether they see me,” she explained. “Do I see me? Am I visible to me?”

The Kindergarten Cop actor went on to call the affair a “major failure” that he will have to live with for the rest of his life.
