Michelle Williams confirms she split from director Spike Jonze in the October issue of Vogue.
"The timing was impossible," she admits. "I thought falling in love again was the only thing that was going to save me from the pain. This erroneous idea: It just makes things more complicated."
Jonze is the first man Williams dated after the devastating death of ex Heath Ledger, with whom she shares a three-year-old daughter, Matilda.
Williams says dating as a single mother played a part in the breakup.
"I obviously don't know how to do it," says Williams, who began dating the Where the Wild Things Are director in July 2008.
Jonze and Williams worked together on indie flick Synecdoche, New York in the summer of 2007. In September of the same year, Williams and Ledger called it quits.
Ledger died in January 2008 of an accidental drug overdose, which Williams still struggles with.
"I was holding it together by a string and a paper clip in the fall and winter," she tells Vogue. "I didn't know if I could keep it all together … You console yourself by saying it's all a deepening process. But it's weird. After the first year, the pain is less intense — it's less immediate. But the magical thinking goes away too. And that's a whole new reckoning."
