You had a small fight with Abby that turned into a huge one.
Lately you've been stressing about little things and they end up piling up, Abby usually doesn't take gratuitous rude comments easily. She tried to be patient for her sake, but even though she was dating you, she sometimes found you annoying.
But the last straw for you was Abby's friend hitting on her and Abby not knowing how to react. The atmosphere in the relationship was already difficult and Abby probably mentioned it to her friends and then Abby's female friend took advantage of it. And you caught it.
"Can you even hear me?!" Abby says impatiently. "Sit down, sit down now." Her tone was commanding and stern.
She was trying to explain herself, but you kept interrupting her because you're really angry and jealous. You were rude to Abby's friends after what you saw, you were rude to her and now that you're back home, she would need to set you straight.
