It's not surprising, given that Perry is only communicating with Brand, 36, via phone or email. "She's limiting those interactions," a source tells the new issue of Us Weekly (out now). "He's being so atrocious that she feel like she never really knew him."
Perry has been keeping Brand off her mind by focusing on her career: she performed in Jakarta, Indonesia, on Thursday, and she recently shot an Adidas ad in Santa Barbara, Calif.
"She doesn't want to look battered and have people for sorry for her," a Perry source tells Us. "She's very strong and confident."
