Back in the day..I too learned about all of this from a counselor. She "saw my wife in action" so I asked her what I was dealing with. She handed me SWOE and I couldn't believe other people had the same life I did.
Anyway...anger and resentment is completely understandable. I'm not so sure I would be in a rush to move past them. They are your feelings and completely valid. My hope is they motivate you to get yourself to a better place.
Have you read the entire book yet (SWOE)?
Before I give you any advice about next steps, I'm curious about what you think you should do next? Anything jump out at you after reading the book?
Did the counselor advise anything?
Please understand we "get it"...we can help you understand all this.
Best,
FF
