My girlfriend wants some space and I don't know what to do?

Me and my girlfriend got big fight last week, I am just yelling at her and somehow I just triggered her trauma (physical abuse by her ex) but I never hit her or did anything physically, and after that she ghosted me for whole day (not reply or answer all my calls) , next day i want to pick her up at her workplace and talk to her, suddenly se replied my text and she told me wants spaces for her to heal her trauma and she said that I’m being creepy to her, she never answers my call my texts anything since that day, so how long should I wait and what should I do now?
