She said: "When you split with someone you love, you think you're the only person who has ever gone through it; 'Oh did you listen to The National on repeat and lie on Marlboro Lights and chocolate for three months? Me too.'
"But I was lucky to have such a peaceful parting. It's never easy, it's f***ed up and I wouldn't recommend it. But there were no kids involved, so we could see it as this wonderful chapter.
"And anyway, you fall in love again. Oh God, to think you only fall in love once in your entire life is such a depressing thought."
Olivia is even considering turning her experiences into a screenplay.
She added in an interview with the new issue of Britain's GQ magazine: "I actually think the subject of young divorce is pretty funny and I'd like to write a movie about it. Can you imagine a young couple fighting over the Ikea furniture?"
