^^^^ yep. I was baffled as to why you had to ignore her text this am?
As for Wonka ' s advice to not respond to anything that's not an emergency. .. I respect Wonka tremendously and think she is often right on the money. In this case, however... I think rule #1 of DB applies: do what works. The ignoring was not working. When you respond politely, you more often than not shut down the center action more quickly and peacefully than ignoring.
I think she will get your message ("leave me alone" ) more quickly with short, unemotional responses than with ignoring.
And if you have been cordial and polite, at some point later you can calmly set a polite but firm boundary.. not out of anger.
