you girlfriend was running a bad fever for the past few day.... You were usually rude and cold towards her... And didn't take enough care of her... Which lead to this.... You were still rude to her after knowing she had a bad fever... And one day... When she was making dinner for you... And after you guys were done eating... She accidentally broke a plate... And you were very mad at her... Despite knowing that she had a bad fever... She was so exhausted that she couldn't even argue back.... You said some things that triggered her past trauma because since she was a kid... She's been through some stuff.... And your yells were getting louder and she couldn't handle it anymore... As she gave in to the exhaustion and passed out
