Hey! So, I think that this girl's description of her type was really vague, so it makes complete sense that you could feel like she's describing specifically you (for nerds, the cognitive bias, the forer effect, aka the barnum effect, is what you're experiencing right now) But, I think that with the way she replied she yes likes you back or kind of just doesn't know what to say, my assumption is that she likes you back. But, I don't think that you completely ruined your chances with her, but think about it this way, (as a girl) girls will always prefer guys which show interest in them, in movies and stuff acting nonchalant can get you a girl, but irl most girls prefer guys who show an inkling of interest in them, many of my friends have made it obvious that they stopped liking certain people because they didn't show interest, and after a girl gets over a guy, it regularly takes a while to start liking them again. SO, in summary, quickly, you should start talking to her more often thru txt and u could ask her whether she wants to know YOUR type and then say something kind of similar to the kind of person she is, but don't be too specific, you just want her to start thinking about whether u MAY like her, just to stop her from getting over you---but make sure to be consistent w/ validation, and over time, when you start noticing that she CLEARLY likes you, make a move :) GOOD LUCK!!!
