Think, is he a good friend to you? Would he lie to you about this craziness? In my opinion, I don't think your friend would lie about such thing. And why did you two break up? Problems? But whatever the reason, you need to talk with her. Tell her that all you want is the truth, no matter what it is, you'll take it for an answer and deal with it. BUT, if she did f**ked him, then you need to get rid of your friend and her. Sorry, but a real friend won't do that to you. AND a girlfriend don't do that. You can't even call that a girlfriend. Ou another thing, if she really did got raped by him, then she wouldn't tell you to stop yelling at him. I honestly don't think she got raped. I think they both went for it. And you need to get rid of them both. Stay strong.
