I got this a lot too. I know how frustrating it is to hear it when their actions show this to be very much false.
As far as it concerns you it is hollow. What they do care about is the pain they are feeling when having to confront their wrongdoing and waywardness. We all tell ourselves stories. They can’t look at themselves in the mirror if they don’t believe they care. That’s her story and she believes it. And nothing you can say or do would change that. It [censored]! Hang in their, man!
