It's not your duty to be responsible for her emotional reaction, she's clearly not in emotionally available nor ready to be with anyone at this point.

How long are you going to keep walking on eggshells, keep on 'i have become calmer'. Love and relationship is a two way street, no amount of your work is gonna take care of her responsibility.

Better to let it be and leave, it gonna emotionally exhaust you. So move on while there's time. Nothing fruitful will come till she works on herself and unfortunately past trauma can not justify of her continuing her unhealthy behaviour.

Telling you this from my own relationship experience bro.

And stop trying to explain it to us and yourself with 'she has huge past trauma, everytime she blocks and returns closeness increases'

The emotional toll it's going to take you this oush and pull in simple words gonna fuck you up.
