I wish I could just tell him all the damage he caused and all the frustrations I still have about it all, but I know it wouldn't make a difference and now I just have to wait for all this anger to go away. Any tips on how to get rid of all this?
Anger, believe it or not, is OK...provided you acknowledge it to yourself and don't allow it to impact your behavior or your decision making. You're right: telling your AXBF what he did would fall on deaf ears and would likely blow up in your face. So what you have to learn how to do is take that anger and live with it in your day to day life. In time, it will ebb and won't dominate your feelings as much as they are now. But If and Only If you do the proper things to take care of yourself.
