AITA for leaving our anniversary dinner after my girlfriend invited her ex to test me?

My girlfriend smiled at me across the table during our anniversary dinner and said her ex was joining us to see if I was “secure enough for the next step.” I paid my share, canceled the surprise her family was waiting for, and told her, “I don’t audition for a future while you keep letting your past judge me.” ---------------🐋Whale Tales🐋--------------- #reddit #stories #redditstories
