Kate Winslet still believes in the "beauty" of marriage.
The 36-year-old actress - who was married to Jim Threapleton from 1998 to 2001 and director Sam Mendes for seven years from May 2003 - admits commitment can be tough but she still wants to be with someone for the rest of her life.
Kate - who is currently dating tycoon Sir Richard Branson's nephew Ned Rocknroll - said: "I still believe in the beauty of committing yourself to another person and, at least, in the idea of marriage as an expression of that commitment.
"Living with someone will always be a challenge, but you hope to be able to find someone whom you can spend the rest of your days."
Kate maintains a close relationship with Sam for the sake of children Joe, eight and 11-year-old Mia - her daughter with Jim - and while the aftermath of the split was difficult, she says they are all very happy now.
She told Britain's OK! magazine: "It's not the easiest situation being a single mother, but Sam has been very good in helping me with the kids.
"They've been spending time with both of us and even though it was hard at first, we're all doing great. I've never felt better. I'm very happy with the work I've been doing and I'm enjoying my time with my children, who mean the world to me."
