There's a different but somewhat related "no response necessary" communication technique my wife and I discovered. This occurred when she would share a problem she'd recently faced with me. Being an engineer, I'd listen to the problem and then helpfully try to suggest possible solutions. Sometimes this was fine but on other occasions, she'd seem to just disconnect or even get frustrated. But which way things went didn't seem dependent on the usefulness of my answer.
The realization came one day when I was kind of disappointed that the comprehensive rank-ordered list of possible solutions I'd helpfully provided only got an annoyed and frustrated non-response. So I pushed back and asked what answer she was looking for. This caused her to erupt and exclaim "I just needed you to say 'That's terrible, honey.'" and then she stormed off. This was a shocking revelation for me.
We discussed it more calmly later and, sure enough, sometimes she was relating the problems she'd confronted not because she wanted solutions but because she felt a need for understanding, empathy and connection. Ah! That's the day I learned to consider (or sometimes even ask) which kind of problem statement this is - and that lets me respond with either solution suggestions or a heartfelt "That's terrible, honey." This has made life better.
