I have found that the anger eventually evolves into feelings of compassion for the mixed-up ex. It's a very slow process and takes an extremely long time. At least for me it is. And the process isn't without it's backsliding. I can be fine for a long time and then something jars my memory and I feel a rush of anger.
The good news is it happens less and less. Eventually, I believe I will only feel compassion whenever I remember anything about what happened.
Have a great day!
