Is it over?

I (17M) had been talking to this girl (17F) from a nearby city for almost three weeks on Instagram. We got along fast, flirting, chats very late at night, she talked about her life and asked about mine. And we have a LOT in common, and from the start it was kinda clear i didn't have friendship intention. She sent selfies, short outfit pics, hugs, kisses, a lot of heart and kisses emojis, even playful jealousy jokes, and vent about her friendships. We talked every single day, and it really felt like something was growing between us. And she has shown interest when i said we could go to a specific place.

Around week 2, I noticed she never really complimented me (not quite her fault), but there were still the flirty jokes and calling something i said "cute". I tried to accept that maybe it was just her way of showing interest, and she is a shy person. Still, part of me felt she didn’t care as much and maybe just liked the attention, cause i complimented her every day.

Then last Sunday night (Oct 5th to 6th), we were chatting about my trip to Argentina and her weekend, she had lots of schoolwork that weekend, so we hadn’t talked much. She even sent me a selfie of her during the chat. I told her I’d send her a drive with some pictures from my trip. I sent it ten minutes later, she suddenly stopped replying. I assumed she went to sleep because she had to wake up early then next day. But the next morning, no reply. She usually texted me back as soon as she woke up, but this time, she didn't, but i just thought she woke up late or something. I texted her at noon and still nothing. The whole day passed, and I started overthinking everything, that she was ghosting me or something.

The next morning, I texted again, asking if she was okay. She replied really normal, “Helloooo I’m goooddd, hbu??” I asked if something had happened, and she said she just forgot to reply. That hurt me a bit. I asked her that if I hadn’t texted again, would we even be talking again, and she just said, "I don't know 😥.”

I opened up, saying I thought the importance we gave to each other was different. Maybe a mistake, but I wanted to be real for once, because we never talked serious about our relation. Then she asked if was already in love with her, I joked “not yet,” and said I really liked her. She replied, "Mmmmm I kinda like you too.....……” (Kinda)

I told her I felt she didn't care much, but that maybe I was just overthinking because of what happened the day before. She sent a sticker of her avatar thinking with a “...” on it. I asked her to be serious, she just sent “👉👈”. When I said “for real,” she answered hours later (Like 11pm) saying she “didn’t know about those things.” I asked what she meant, and she said, “I just don't know.” So I told her I’d been honest about how I felt, and hoped she could be too, but she didn't reply. It’s been almost three days now.

Maybe i shouldn't have done that and should've waited and talked to her normally again, but i couldn't avoid it when she said she forgot me (She once said she forgets people, but it doesn't make sense to me when we used to talk all day and night)

I don’t know if she just saw it as casual flirting and she genuinely doesn’t know how to deal with something serious, or if she is waiting for me to go after her. I really liked her and thought we were going somewhere, maybe even planning to meet soon, but now I’m kinda lost.

Should I text her again, wait or just let it go?

TL;DR: Talked to a girl (17F) for 3 weeks, felt a connection, but she ghosted me for a day and got vague when I asked about her feelings. Should I text again or move on?
