One of the biggest things that I've come to realize is that despite my PO parents saying I was their priority they failed to move towards me when I needed them most. It's their lack of attunement that hurts.
I try to talk about this in therapy but I still seem stuck. I wake up in the middle of the night angry, sad, and crying.
Even trying to set boundaries and communicate them to him leads me to rage and sadness. For years I didn't recognize that when I've spent any time with him it usually takes several days to come back to being fully regulated. I could probably recover faster now that I've been to therapy, but I'm frozen in fear that he'll try to use his wealth to try to control me and the decisions I make for my family.
There appear to be a few folks who answered my question.
