American actress Michelle Williams, the winner of the 2012 Golden Globe for Best Actress in a Motion Picture (Musical or Comedy), spoke to GQ magazine, about her relationship with one-time fiancée Heath Ledger. Williams also spoke about Ledger's death, in 2008, and how it affected her acting career.

She met Ledger, an Australian actor, in 2004, on the set of Brokeback Mountain. The couple announced their first child together within a year, a daughter, Matilda, who is now 6.

Our initial meeting, the circumstances of how we first met, were cosmic or something, Williams told the magazine. Yeah, a lot of things happened at once. It's a bit like: We had a lot of things to do, because we didn't have a lot of time, or something, she added.

The couple was together for 3 years, before Ledger died in January 2008 from an overdose of prescription drugs. Williams added she almost quit her acting career at the time, because of the media's unwanted attention and the need to protect her daughter.

It was making me crazy. I felt like I was going crazy. It was too much... I just felt trapped. And it's not just me - there's somebody else who I'm trying to protect, and I can't. I can't make it stop; I can't make it go away. Trying to find ways to explain it or shield her from it. It's like you're trying to go about your life, and make dinner...but the roof is off of your house, and the walls are falling down, Williams explained.

The former Baywatch star, who temporarily refused to commit to a project after finishing Martin Scorsese's Shutter Island in 2010, said she had hoped to reunite with Ledger, despite their break-up in 2007. In a 2010 interview, she'd said she found it very hard to believe he was dead.

In a strange way, I miss that year, because all those possibilities that existed then are gone, she said, It didn't seem unlikely to me that he could walk through a door or could appear behind a bush. It was a year of very magical thinking, and in some ways I'm sad to be moving further and further away from it.

When GO asked Williams if she ever imagined a possible future with Ledger, she replied: It would make me too sad to answer, but it's also one of my favorite things to imagine. It's actually one of my favorite places to visit.
