And it wasn't entirely pointless. First, she was planning on being in town to pick up the pile of stuff which has been in my garage for 4 months, and so I told her to send a concise message with details and I would arrange for a representative to open the garage but that I had no desire to speak with her and would prefer she not come into my house. Secondly, I needed to write the bit about releasing her from her vows, for me.
But yes, still probably unwise and it should have waited a couple of weeks. But we'll see what the aftermath is.
