You are handling this well. Make sure you are the better person and handle this in a way that will make your family, your kids and you proud.
She is still way deep in the fog of alien land. Continue to focus on you but listen to her when she spews. The advice that was given to me was to really listen to the stuff that hurt the most. This feedback is probably dead on and something on which you need to work.
Would keeping the house cleaner be a 180 for you? Perhaps doing this would (1) show her that you do not need her and (2) demonstrate that you are moving forward. My W always made the bed in the morning but now never does. So I make it every morning. Why? To show her that I am moving forward and do not need her for anything. Not only might this attract her back, but it also is preparing me for what could be the inevitable (being a single dad). In the case of the latter, I will need to make meals, make the bed, clean up the house, etc.
Finally, next time you do not reply to her texts, perhaps instead of "I heard you" respond with "oh, sorry, I have been super busy, just getting to your texts now." I heard you sounds like you were stewing a bit and angry. Anger will not attract her back. Confidence will. As the vets have tried to drill into my head, be happy, positive, confident and strong.
Keep on truckin'
