Angelina just couldn't come to terms with it. If he had really changed, wouldn't the change in his personality withstand even if he couldn't remember why he had changed? She knew that she should never have started the relationship shagging him straight off. She had no way to know if she was really a romance or just an exclusive fuck buddy.
Angelina couldn't even speak. There was too much going on in her mind and she didn't want to say something she'd regret later.
