Go to the store right now and get yourself a mini-tape recorder and start taping your conversations with her. Get your to say she fucked yourself up on tape. After you get that on tape, make a copy keep it out of the house. If she does get the cops involved, you will be arrested no doubt about it. After she admits to beating yourself up on tape and you have a copy in a safe place, make sure you tell her that you don't trust her and that you are taping every conversation you ever have with her from here on out. When the cops tell you that you aren't allowed to tape anyone who doesn't know they are being taped, you tell them that you told her that you are taping her.(even if you didn't tell her before she admitted to beating herself up) who cares, the cops will have to drop it all because it will be on big cluster fuck and in most cases they will listen to the tapes and realize she is fucked. But keep copies in a safe place. And if cops ask you if there are copies tell them of course there is.
