Shriver's divorce petition was filed July 1, 2011 while Schwarzenegger did his own filing later. They both sought joint custody of their children.
The former Governor and his wife separated after Schwarzenegger admitted to having a relationship with the household staff member who served for him for more than 20 years. He said he apologized to his family for the secret love affair.
In an interview on Piers Morgan show Tuesday, Schwarzenegger said he still loves Shriver and wants to win her back.
"It's my fault. There's no one else to blame," the former California governor told CNN
host Piers Morgan. "I ... screwed up badly and I take the full blame for it," he added.
"I love my kids dearly, and I love Maria ... She has been truly the only love that I've ever had and that's what is so pitiful about it," he said, describing her as extraordinary and "the most perfect wife."
Schwarzenegger has four children with Shriver and a son with Mildred Baena, his former house maid of 20 years.
Schwarzenegger has released his "tell all" book last October 1 entitled: "Total Recall". One chapter of the book is all about his highly-publicized family scandal which ended his 25-year marriage with Shriver.
The rest of the chapters in the book talks about his life as a former body builder, being a box-office action star and his six years as Governor of California.
There are reports
that Schwarzenegger's talks of reconciliation with his wife has got something to do with the launching of the book.
