Hi David
It might be reasonable to block her or not respond but you have already stated that you are refuse to do that.
This is why it is good to discuss alternatives.
How would you expect a future partner to react to your ex divulging these things? How does this make you feel?
You could take the power out of this threat simply by explaining to any future partners about that partner. How does the idea of doing that make you feel?
You could even talk to your employer and tell them that you have a disgruntled ex incase she tries to get in contact.
