This concept of wanting an apology is totally normal. I am 5 yrs. post BD and divorced. I no longer crave it because I know I truly deserve it. I was far from perfect. But I deserved better - not because I am so great, but rather, because his treatment towards me was so disproportionate to what I was owed after so many good years.
This is on them. In the end, I feel sorry for them. Stable people don’t do these sorts of things. They have lost the plot.
