For me, anger was part of the healing process.
First I was angry at him, angry for the lies, chaos, and of course his unwillingness to choose me and not the booze.
Before I knew it, I was angry at myself for accepting his unacceptable behavior for so long. I felt like a complete failure.
I stayed angry for quite a while, until one day i realized that I could not change the past. I could not rewrite our story, not one thing could I change, this is just how it had to play out. With some time and distance I decided to leave the past in the past, live my today, and look forward to the future.
I think you are just responding the way anyone would who lived in an addicted home. Wishing you peace and sending healing thoughts.
