Yes. this happened to me. there was this one girl in my class that was kind of nice and good-looking. (I did kind of like her) and around a week after we met she seemed to show some signs of interest (pupil enlargement, blushing, initiation of conversation, etc.) and then it hit me. self-doubt, fear of commitment, and awkwardness. and I was going to end up asking her out but it came out as hello, you look nice today. yeah. the end. that is the story of why I have been single all my life lol
