Awake,
I scare myself too sometimes
I am so sorry you are going through this. I do think your feelings are normal considering what you have been through. 33 years is so long, my relationship was not nearly that long but I can tell you that I feel a setback each time I connect with my ex. (We work together). I do feel things are getting better though.
Something that you wrote, the grieving is not as intense, so that shows you are making progress and that is good.
Have you read this book?
The Betrayal Bond It really helps me. There are exercises in it, and I find myself going back and reviewing it a lot when I have these setbacks.
