Sienna Miller and Rhys Ifans
06/20/2008 AT 10:40 AM EDT
is holding up after the widely reported break-up with her boyfriend
, Welsh actor Rhys Ifans.
Her life, she tells London's The Times
while promoting her new movie The Edge of Love
, is "exquisite. I'm not victimizing myself, I'm not this tragic figure."
"My life is privileged," says Miller, 26. "And it's exactly where I'm supposed to be. I make decisions. I take responsibility for them."
One recent decision: to sell the Central London home she shared with Ifans, 39, best known for his role as Hugh Grant's eccentric roommate in 1999's Notting Hill
"I want to sell that house," she says. "I don't like it any more. I'm over it."
What is difficult is escaping the news of her breakup. "It's everywhere," she says. "I try not to read it, but it's hard not to. I don't want to go, 'Woe is me in suffering', but it's not easy for me."
When it comes to settling down, Miller has admitted that she "chops and changes." She admits to sexual experimentation with other girls as a teen while away from home at Heathfield boarding school in Ascot.
"It was a great school, and it made me learn how to share and to understand women," Miller says. "We'd have the odd snog together. It wasn't all the time, but, you know, who hasn't dabbled?"
