It's been exactly one year since Ryan Reynolds and Scarlett Johansson announced their divorce, but the We Bought A Zoo star has no regrets.

In a recent interview with Cosmopolitan mag's January issue, the blonde beauty opens up on her two-year marriage to Reynolds, calling it "the best thing I ever did."

Johansson reveals:

    "I'm a big believer that when something feels right, you should do it. I'm a big believer in instinct. Getting married was the right thing to do because it was natural. It grew out of a romance and love and a desire to have a future with somebody, and I was very fortunate that I married somebody who turned out to be the person I thought he would be."

The Avengers star adds,

    "Relationships are complicated. Being married is a living, breathing process. I think I was not fully aware of the peaks and the valleys. I wasn't prepared to hunker down and do the work... Both of us were extremely busy. We spent so much time apart. It's very difficult."

But the newly single 27-year-old says she misses "having a partner and a confidant."

While ScarJo moved on with actor Sean Penn after the divorce -- the pair have since broken up -- Reynolds has been linked to former costars Sandra Bullock and Blake Lively.
