What MTB said is accurate. Truthfully you are in a no win situation with her right now which should really drive home the importance of NC unless absolutely CRITICAL.
My guess is every time she gets a text message from you she just cringes. You really have to leave her be. I think at the height of my EW's anger towards me I might have only contacted her once a week and that was to organize kid drop off. There was literally no other communication and when I did drop the kids off it was high and by. 5 min's in and out.
I can't stress to you enough that you really need to let her be....let her come to you.
