Need advice on this situation [Read body]

I'm keeping it short. Well, this might be stupid too, but umh...

We used to talk and had a good bond in terms of similarities and interests. We even talk on call for like hours at night(like from 10-12) and she shares her stories and sometimes we flirt too. But I did something stupid (it was my fault, I know) and then she got angry(it wasn't a big deal, but she made it a big deal) so, I thought let's give it a little time, it might get better. I hadn't texted for days thinking if she was interested then she would do, right??? And she did, but saying that I disappeared 🙂 like wow??? Can't you text at all ?? So, that text from her, I tried to call, and she wasn't interested 🙂 wow?? Nice. And these games fucks my mind and overthinking keeps going. So, I thought it was clear that she wasn't interested, because if she was, she would've reached out or put some effort.

Well, it's been a month and tomorrow I put a story(Instagram) of myself with a song, and she likes that story. What does that means??? What should I do? Or just leave it as it was. I never thought we were going to talk again.
