How to respond to estranged spouse <

First, this work is incredible. There’s a significant and measurable change in how I feel in the day and how I interact with the events of my life. I’m applying the 3 q’s constantly, and when it’s available, just repeating a recent new thought that’s addressed one of the 3 main “negative” feelings I’ve lived with. Incredible shifts. Thanks.

Question: My estranged spouse likes to say things like, “You hurt my feelings” and “I found your response dismissive.” I don’t know how to respond so I frequently say nothing – a pattern that’s not helped our relationship. I want to say, “I don’t hurt your feelings, you hurt your feelings. I can’t be responsible for your feelings anymore.”
