She called me bro, is it already over?

So there’s this girl I kinda like from college, we hang out not just in college but outside too (but most of the times there’s other people too). She makes sure to chat with me every once in a while since she’s been out for education and we share posts to each other (she posts like frequently but I post most of the times but she still makes sure to respond to most of them). She never called me bro before and we’ve known each other for 3+ years. Today I asked her to send me some videos for the concert tomorrow and her response was “you remembered the concert bro” and like it was like a knife through my chest. So like I kinda feel down right now and wonder like should I still have my hopes or am I actually cooked?
