My opinion? I don't think you'd be making things "worse" by not responding. I suppose the question that would follow is, between the times that you are not making things worse, what are you doing to make things better?

My W and I are stuck on the "no contact" thing. She doesn't contact me and I don't contact her. Unless it has something to do about the kids. Later, it will include the money stuff...

Back in the day, when I would contact her with stuff and she wouldn't respond, it would make me mad. When I finally confronted her on this (in a passive way), she simply said that either she had nothing to say, or she was thinking about the stuff that I had said.

Now that I don't contact her and don't respond to her every contact, she tells me that I've made it very clear that I don't want to talk to her... double standard...

The point is, my W is still mad at me. Not sure why. Not really worried about it. That's her stuff. And so now her anger comes out in different forms at different times. To (like you) sending D8 home with a rash on her face, to telling me that I have to work on my issues with D13, to telling me that I must be mad at her because I'm not contacting her, to telling me that I'm snooping in her life when I truly have no interest in her life any more.

I can only guess that your W is going through the same type of thing. Now that you are not jumping every time she contacts you, you are doing the opposite of what you have done in the past, and it's unexpected, she's lashing out to see if she can push your buttons into responding. Get you back to what she expects and her form of "control". Not saying she's controlling, but she needs that consistency.

Back to cognitive dissonance... We live in a world that we expect. We have learned to be comfortable in that world. So when we throw a ball in the air and it doesn't come back down to earth... well, that really blows our mind. We have trouble integrating this new reality.

Let her struggle with that.

Here's the question(s):
Do you need to respond to her every text? ie. Is it life threatening? Do you need to contact her often to chat about nothing in particular or about the R or telling her what you are doing and the details of such?

I'm guessing the answers are no.

So try not to sweat it. Her reaction to your indifference is for her to deal with...
