Susan Sarandon has no regrets about ending her relationship with Tim Robbins.

The Oscar-winning actress, who split from 'The Shawshank Redemption' star in 2009 after 23 years together, has revealed she decided to leave him after starring in the comedy about death, 'Exit the King,' on Broadway in New York City that year, as it made her examine her own life.

The 'Stepmom' star told the February/March issue of AARP The Magazine: ''You can't do a meditation on death and stay in a situation that's not authentic. It made me examine where I was in my union and in my life, and to have discussions about making changes.''

She added: ''It's better to have made decisions that turned out badly and learn from them than to feel as if you had no choice and are resentful of the turns that your life takes. My life has been filled with happy accidents. The thing that's served me well is being able to change onto a different track when it's presented itself.''

The 67-year-old star, who has two sons, Jack, 23, and Miles, 20, with Tim and a daughter, Eva, 28, from a previous relationship, also admitted for the first time that she is dating her business partner, Jonathan Bricklin, 36, despite previously insisting they were just friends.

She said: ''Jonathan and I collaborate on different things. That means a lot of things.''

Asked if that included romance, she said: ''Yeah, I think so.''

The couple, who were first linked in 2009, sparked rumours they got engaged late 2012 when they were spotted looking at jewellery in Amsterdam.
