I broke up with my ex many months ago, yet I still have a lot of anger with her. I think it's important to note that I was the one who ended the relationship -- otherwise these feelings of irritation and anger could be misconstrued as feelings of jealousy or longing. They are not. This person isn't even in my life anymore, yet whenever I see her, I get angry. When I hear something about her, I get angry. And when I get angry, I obsess over the anger. I think about how much she used to anger/upset me, and then I stay angry for a long time. How do I overcome this? It's not healthy for me to constantly be this upset. I have no interest in ever talking to her again, and I do not miss her. I just want to not care instead of being angry.
