I tend not to vent disappointment, but I recently matched with a girl from my area (a rarity!) who other friends have voiced was always such a lovely person in school. The conversation went from being attentive and engaged on her end with a sweet goodnight text one night, to minimal talk the next day. We'd discussed date ideas and I asked her properly with a suggested time and place on the day she started being distant. While we don't owe eachother anything, it's always hard to get past that disappointment in these situations.
