AITA for canceling our plans after my girlfriend spent our deposit on her ex's legal bill?

My girlfriend drained most of the money from our apartment deposit to cover her ex’s legal bill, then said I was too insecure to understand loyalty. I only said, “Got it.” By sunrise, every plan with my name on it had been canceled, her story about being the victim was falling apart, and her ex was already asking her for more. ---------------🐋Whale Tales🐋--------------- #reddit #stories #redditstories
