Input: I had been dating my girlfriend for about 6 months. We both earn a good income. She called me at work and wanted to see if I could have dinner with her and her BFF. I agreed and when I arrived, they had already eaten and had had two drinks. I ordered for me and also ate. When the check arrived, she expected me to pay. I gave her some money but not for the whole amount. She was visibly upset and mentioned that I should have paid.
