Am I a bad person

A friend of mine is the type of guy that has more than one woman to mess with. He says that one girl can't satisfy one man. He has a wifey, a girlfriend and then he has hoes.. I'm friends with one of his hoes, and she cannot get over him. Mainly because he took her virginity and he played her, but she doesn't realize this. Is it bad that I am not telling her the plain truth, and that I'm going along with his lies?
