Actress Michelle Williams is keen to make a clean break after splitting up with boyfriend Heath Ledger - she's looking to move to Portland, Oregon. Friends claim there are too many bad memories for her in New York, where she shared a love-nest with her Brokeback Mountain co-star, and she fell for Oregon during a recent break there. A source tells In Touch Weekly magazine, "The split with Heath was pretty devastating, and Michelle wants to start over." Williams and her two-year-old daughter by Ledger, Matilda, recently spent time with friends in Portland, and now she's reportedly looking to create a base there. The insider adds, "She's able to relax and unwind when she is here."
