If you sent anything else, I would not finish it or put anywhere in it, a question. Give her information, not an opportunity for conversation.
Unless it's what you want...
But you will get conversation if you indicate that you are concerned about your D and how you feel she is hurt by your X.
Before denying your X access to your D, I would talk to your D and try to dig how she feels, without putting her into a position where she feels she needs to communicate with X, if she does not want to.
