have you tried mentioning it to her? if she believes in magic and whatnot, telling her about the readings might help her out, but if she doesn't believe in such things then telling her might make her more distant from you. or perhaps suggest she start carrying mace or a small knife or something in her purse for protection against generic bad peoples (ie, don't implicate her boyfriend but make sure she is protected none-the-less).
and also, you might want to read material on how to deal with and help rape victims so that if it does come to pass you'll be there to help her as much as you can.
