i (19F) lived with another girl in college. she consistently would eat my food and when i caught her said she would “replace it”, but never did. i finally got a mini fridge for my room and started labelling what i left in the kitchen. she was calling me “petty” and told our friends i made the apartment “hostile” (really don’t know how it was my fault). i just don’t think i should be feeding the both of us. AITH for locking up my food?
