Today at school a rumor started floating around by my ex best friends ex boyfriends saying that my boyfriend raped her. Even though we don't have proof that he said that through text the school wont do anything. Its false accusations of rape on his part and the girl has confirmed that its false And they still wont do anything. I don't know what to do. He's been with me for the last year and I know this isn't true. But still what can I do to make the school or someone realize that this accusations are wrongful and that we should press charges against him for slander

I just don't know what to do?

Help
