Dealing with emotionally volatile exes when you have kids together is a long, long road. You need to use all the tools you have. No response is one tool. Validation is one tool. There are many other communication tools that a person needs to learn and use when dealing with difficult people and difficult subject matter. Over the course of the D and the rest of your lives that you have to co-parent you need every single tool at your disposal. And sometimes you need to use more than one in one sitting. No response is just a useful as validation.
