Narcissists don’t want to understand anything to talk to them about and many times simply refuse to even if they do understand. The only exception is if it benefits them.
This, of course, increases your confusion and frustration, which helps keep them in control.
Only explain what you absolutely must and let the rest go.
If they don’t seem to get it or understand, they’re probably not ever going to simply because they don’t want to. #grownostr
