The actress, 30, has been dating "The Hurt Locker" star since last year, and she insists their relationship is perfect just the way it is.
The "Don't Trust The B---- In Apartment 23" star tells Playboy magazine, "I was never the little girl who dreamed about a wedding or a big white dress. I don't think I'm sour on marriage. I just don't know if I'm the type.
"Marriage seems scary to me. I'm in a serious relationship. We have a dog together. We live five minutes from each other. It's heaven. I think that might be the key: separate houses, separate bank accounts. Why mess with that?"
