BERLIN: Isabella Rossellini had to undergo therapy after splitting up from film director David Lynch, the "love of my life," the actress and model told a German weekly on Thursday.

"David was the big love of my life. And I believed that he loved me the same way, but obviously I was mistaken," Rossellini said in an interview with Die Zeit. "All my instincts told me we were a happy couple, but we weren't."

"I spoke (afterwards) with other women who had been through the same thing. And I took therapy. But the thing that helped me the most was time," the 57-year-old said.

Lynch and Rossellini, the daughter of "Casablanca" star Ingrid Bergman and Italian director Roberto Rossellini, became a couple after acting in his 1986 classic "Blue Velvet". She was previously married to the director Martin Scorsese.
