She and Woods will share custody of their children, Sam and Charlie, 1. The terms of a monetary settlement were undisclosed, but Nordegren will be wealthy.
While she admits the money will make things easier, she told People: "Money can't buy happiness. Or put my family back together."
Her 2004 marriage to Woods was one of the happiest days of her life, she said.
The two met on the PGA tour when she was working as a nanny for Swedish golfer Jesper Parnevik's children.
She initially was wary of becoming involved with Woods.
"I had my opinion about celebrities," she said.
But she found out that they had a lot in common, and they dated. When he proposed, all her reservations about marriage vanished in that instant.
"I loved him, we had so much fun and I felt safe with him," she said.
Her healing has involved intensive therapy, and the help and support of family and friends. She kept a journal to document her feelings and to her release anger and frustration.
But she credited her children with being the reason she made it through the disintegration of her marriage.
She recalls sitting at a table in the home she had rented after she moved out. It was around Christmas, and she was surrounded by boxes on the floor.
"I wasn't crying, but I was thinking and was sad.
Sam came up to her and rested a hand on her mother's cheek. In Swedish, the little girl asked: "Mommy, where is your boo-boo?
"I smiled at her and said, 'Mommy's boo-boo is in her heart right now, but it will be better,'" Nordegren said. "She looked at me and said: 'Can Sam kiss it and make it better? Or maybe popcorn will.'"
A psychology student, Nordegren said she went through the classic stages of grief.
The final stage is forgiveness. She can't forgive her ex-husband just yet, but says she's working on it.
"I know I will have to come to forgiveness and acceptance of what has happened for me to go on and be happy in the future," she said. "And I know I will get there eventually."
Nordegren is excited about her future, and also expects to date again, but not for a long while.
"I believe in love because I've seen it," she said. "I've been there."
