Wow, I'm so sorry to hear about this, Seamy. That must hurt terribly to be so coldly shut out and then falsely accused like this. I'm sorry, man. These relationships can be immensely painful sometimes.
As you know, pwBPD can split us. We are sometimes split white where we are the greatest person in the world, and times when we are split black and we are the worst person in the world. This is one of the common coping mechanisms of the disorder. It's a way for pwBPD to seal themselves off from the agonizing pain of loss (you are a horrible person so I don't miss you), and to externalize tremendous shame by making it someone else's fault. That might well be what is going on here with your partner. When the emotions have cooled and your partner is closer to baseline emotionally, she may stop the splitting. It's hard to know how long that might take, however.
The important thing right now is to protect yourself. If the police are involved, you must take it seriously no matter how unfair you feel her charges are. For now, let her go. If she contacts you in the future, you can see what happens. In the meantime, try and take good care of yourself. This is a very difficult experience - it has been for all of us. We understand. So, right now take good care of you.
