"She is broken-hearted," a friend tells PEOPLE in the new issue.
For Shriver, who has moved out of their Brentwood home and is currently living in a Beverly Hills hotel, it's been a time of sadness and immense pain.
Schwarzenegger, 63, told Shriver, 55, about the secret child earlier this year after he finished his second term as Governor of California. "The magnitude of this betrayal knows no bounds," says a friend of Shriver's. "She had no idea."
Shriver said in a statement on Tuesday that she's focusing on her four kids and asked for "compassion, respect and privacy as my children and I try to rebuild our lives and heal."
Just how she'll begin to pick up the pieces remains unclear, but those close to her say she'll do whatever it takes to protect and be there for her the kids: Katherine, 21, Christina, 19, Patrick, 17, and Christopher, 13.
"No matter what, she will take the high road," says a political source. "That's her style and that's her family's style. That's just who she is.”
