AITA for packing my girlfriend's bags after she planned a night with her ex?

She said she was meeting her ex for closure and warned me not to make it weird. So I handed her the overnight bag she thought I didn't know about and said, "Don't worry. I already packed your exit plan." The look on her face told me I had finally found what she had forgotten to hide. ---------------🌞Sunny Stories🌞--------------- #reddit #stories #redditstories
