Guess I am still in the dinosaur age, but I don't think these types of conversations need to take place through texting.
What could you have done differently when she called you cursing and using all kinds of vulgar name-calling?
When you told her you would no longer tolerate her talking to you in that manner (which is certainly a needed boundary), what did you have in mind to use as a consequence if she does not honor it?
You cannot reason with a WW, and if she's so angry she is throwing that kind of fit.......it is a waste of breath to go into any explanation with her.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
