In a case like this, I would feel hurt too. You are not being unfair. She messed up by revealing her true feelings by thinking out loud. If it was me, I’d cancel the appointment for New Year’s Day. I’d cancel for a couple of reasons: 1) She’s human - we all make mistakes - there is room for error in relationships; and 2) I’d rather get a “better version” of my T on a day she truly wants to be at work. That’s just me, though.
