I have spent a whole lot of my life thinking that my feelings weren't okay. It hurts so much to feel that way. One thing that stands out to me is when he would constantly criticize me, I would say" Let me know if I do anything right today? Kind of as a joke, but not really...
I know the anger, and yes, you have every right to feel angry. Don't supress the feelings, as I did for years.
I'm so sorry you are dealing with this right now. Love and prayers
