This would line up with a broader trend I've noticed and would be interested in reading more about: the use of pop psychology to justify antisocial behavior.

Ten years ago, telling a distressed friend you don't feel like hearing about their problems would be incredibly rude. Now you can find NYT articles explaining how to couch the same sentiment in more acceptable terms like, "I don't have the bandwidth to perform that kind of emotional labor right now."

Same thing here. Telling a person you wronged to "get over it" is unacceptable. Telling them that you've been working on letting go of negative feelings about the past and being more mindful of the present, and you hope they can do the same? Well if anyone has a problem with that, you don't need that kind of energy in your life!
