If you let her go and she knows that it was not her fault. No matter what you do later, she won't come back. Just like, when a bird is freed from the cage and never looks down again.
No contact with each other but love each other very much. One is in ego and the other is in hope. Waiting for each other who puts down the arrow first leads to a journey to nowhere in which the love bond is broken in such a way that it can no longer be repaired.
