Interesting article. I understand what you're saying here.
Apologies are interesting things. It's what everyone ends up remembering. The, I'm Sorry, repeated four times. But it's the underlying conversation that is far more important. For it's all about understanding what hapened. Why "it" was said, what they meant, was there something earlier not resolved? Apologies are a process not merely the end result. If someone is resistive and doesn't get why you don't feel better (a little too much force there) they're probably hedging and not really accepting their role in it. Saying and meaning, I was a Dick, takes a bit of courage.
I think it was courageous for you to reveal your process here. It is scary. 👍🌹
