Idk you might be right I may really just be playing myself. Hard to say right now, because truthfully I haven't had much time to process these things, I've only known this girl since like mid-October, shyt almost felt like we went through all the main stages of a relationship in a matter of 2 months w/o even being in a relationship, And at the end of it she was saying shyt like "I can't do this anymore", "I need space", "You really think I'm stupid", "I don't even know what to say", "I don't know how to feel towards you anymore", etc etc
use this to learn about yourself breh. why did you need her so much? why did you want her to like you so much? when it was clear she didn't want anything romantic, why was it so important for her to be your friend? why did you seek her attention and time so much? why did you need her to not be mad at you over what you said when she misunderstood? why were you so scared to let her not be part of your life anymore? why did you need her not to hate you and to understand you?
if i was cool with a chick, i don't think it could have ever gotten to the point where she's telling me these things because i would have sensed shyt wasn't cool WAY before that. Seems like either you lacked the awareness to notice something was off and that she didn't want to be cool with you like that OR you sensed it but were stubbornly trying to fix things so it could be like when y'all were laughing/flirting again. these are all questions you should be asking yourself but first you gotta accept responsibility
