Hi Morbs,
What you described is similar to what happens between me and my BS.
I don't have a solution or particular wisdom to share. I am learning to detach during these triggers: not in the sense that I don't have empathy or don't care about my BS' feelings, but in the sense that I don't take his reaction as a personal attack to me. I engage very little with the conflict and I focus on listening while I mentally remember why he is triggered. Truth to be told, sometimes I mainly focus on thinking why he is triggered so I can stop myself from reacting or feeling too crushed.
This is how I usually manage the "regular" triggers.
I am not saying it's easy, sometimes I feel like a pressure cooker, the pressure always going up and I am a split-second away from exploding. Don't.
Occasionally, I am feel that in that specific moment I don't deserve the harsh words, because I wasn't doing anything wrong (in the present). But I focus on the fact that those reactions come from my past behaviour. It's still very hard though.
Like you, I also feel like I am building a "new self". I don't know if the following will resonate with you, if not, ignore me!
You described your new self like a newborn fawn learning to walk on her wobbly legs. And that you want to protect her. What about if this newborn fawn was actually able to deal with all of this? She doesn't need protection from your old self, she is the protector, she is the best version of you, what you actually need to be to navigate this and become who you want to be. She is an active actor. When shit gets hard, she doesn't need to be protected or to escape.
(Obviously this doesn't mean undertaking all sort of abuse. I am talking on the assumption your BS' reactions are in the range of a BS reactions. Which can still be feel extremely raw and rough).
Hugs
WW
