[{"role": "user", "content": "I'm trying to express a romantic sentiment in Italian. Can you help me translate the sentence 'You were mine.'"}, {"role": "assistant", "content": "That's a beautiful sentiment! The translation of 'You were mine' in Italian is 'Eri mio.' or more commonly used 'Tu eri mio'. However if you want to express 'You were mine' as in past tense 'You were my girlfriend/boyfriend' or 'You were my partner' you can say 'Tu eri mia/mio' or 'Tu sei stato/a mia/mio'."}]
