so i (f17) have a crush on a guy from school (m19). we are not super close but we are pretty good acquaintances. we have a mutual friend (she's my close classmate and his best friend) and she seems to always be mentioning him to me even though she doesn't know i like him (she's been doing this since before i even developed feelings for him). at first i thought she might like him but she's been dating someone for over 2 years and i've never noticed any flirty behavior between them. she usually says things like "what do you think of *crush's name*?" or "*crush's name* would have said the same thing". i once mentioned to her the fact that i was a bit scared of taller guys since i'm super short myself and she asked me if i was scared of my crush (this was also before i liked him). could this be a sign that my crush likes me back or am i just overthinking things?
