How did you stop being angry?
I'm so sorry for the delayed response on this! I just saw it.
I haven't completely lost all of the anger, but the anger that remains is really not about my ex at all, it's about me.
On the surface, it's because she didn't do what I wanted her to do, how I wanted her to do it, and when I wanted her to. It is based on expectations that I unfairly placed on her.
But, it's where those expectations came from that is really the issue. My own insecurities and feelings of being "not good enough" are what caused them to exist in the first place. So, I'm angry because I didn't feel good enough for her. It really has nothing to do with her though; it's all about how I view myself.
The other anger issues were easier to deal with, I simply forgave her. I found compassion for what she is going through, and understand why she did what she did. I also understand that those things had nothing to do with me. She was lashing out at me because of how she felt about herself.
