Am i being delusional about my talking stage? Me (26M) and (23F)

I met this girl at a tattoo convention months ago while I was chilling with a friend who was getting tattooed. She popped over to say hi to the tattoo artist, who is a friend of hers, and she introduced us, saying she was exactly what I was looking for for a tattoo. We talked for a bit there; she told me she was going through some stuff and isn't tattooing anymore for now. Eventually, the conversation died out, but I didn't think much of it.

The other day, while I was slightly drunk, I replied to one of her stories, asking if she had started tattooing again. From there, we started talking for hours. She really opened up, she was flirting, and she told me she’d like to talk about it in person. Then out of nowhere, she vanished. I didn't think much of it at the time since it was 4 AM and I could barely keep my eyes open either.

The following days, though, the situation didn't change. She only pops up in the evening when her work shift ends, sending tons of messages, flirting, selfies, voice notes, and hearts, and then she disappears without saying a word. The other day, while we were flirting, I told her that we should definitely meet up, and she hasn't replied for two days now. Am I getting too attached, or is something going on? What the hell

Anyway, she had also said she wanted us to meet up, and to take it slow with her because she's going through a bit of a rough patch. Still, I don't understand why she would show so much interest only to then disappear.
