I just realised that I don't need to be angry with her anymore. She will have to live the rest of her life with what she did, whereas I don't. I get to go and be awesome and do awesome things!
Just be careful because anger is a valuable part of the healing process. We go through the 5 stages of grief for the end of the relationship same as other loss. Denial - Anger - Bargaining - Depression - Acceptance. And sometimes bounce around back and forth between them.
I think the key is using the anger as a fuel for you rather than as a way to attack to her.
