The 49-year-old English actress discussed the 57-year-old American director in an interview for the publication's November issue. Carter and Burton were together 13 years, and announced they had ended their relationship in December 2014.
"I think we'll have something very precious still," the star shared. "Our relationship was always somewhat special, and I think it'll always remain special. We did find each other. And really, the mark of a successful relationship shouldn't be whether you're there forever after."
"We gave each other children and a lot more else," she mused. "And we might be better, and still be able to give to each other, but not necessarily living together. Which we did by the way, because everyone seemed to think we didn't, but that was a load of myth."
Carter and Burton share two children, 11-year-old son Billy and 7-year-old daughter Nell. The couple met on the set of Planet of the Apes in 2000, and the actress would go on to star in several other Burton films, including Sweeney Todd and Alice in Wonderland.
Carter will next appear in Suffragette with Carey Mulligan, and is also scheduled for HBO series Codes of Conduct and BBC miniseries Love, Nina. She will reunite with Burton on Alice Through the Looking Glass, which the director is producing.
