“Maria and I went to counseling once a week,” Schwarzenegger recalled in the doc, perPEOPLE.

She wants to know if you are the father of Joseph.'”

“I thought my heart stopped,” Schwarzenegger admitted.

“And then I told the truth.

‘Yes, Maria, Joseph is my son.'”

Schwarzenegger called Shriver “the perfect wife” and remembers begging for forgiveness after owning up to the affair.

In the new docuseries, he said that following his admission, Shriver was “crushed.”

Schwarzenegger continued: “I am going to have to live with it the rest of my life.

People will remember my successes and they will also remember my failures.

This is a major failure.

“It was wrong what I did,” the former governor added.

I love him and he has turned out to be an extraordinary young man.”

The affair came to light following Schwarzenegger’s second term as governor of California in 2011.

He and Shriver announced their separation in May of that year.

I have apologized to Maria, my children and my family.

I am truly sorry."
