Im so confused on what’s going on

(Sorry In advance it might be a long one)

Hi, so a bit of backstory I 18M have been chatting to this girl 18F who lives near me (yes we’ve face timed and spoken) she hit me up and we got talking. After a while of it was very obvious she seemed to be really, really into me. Sending me flirty and sometimes sexual messages and pictures and giving me loads of compliments. After a while I seemed to really be fond of her too as our chemistry was really good and it’s something I’ve not really experienced before especially with someone who reciprocated the same feelings as I had for them. Just as when we were about to take it to the next level eg meeting and dates etc. Maybe 2 weeks ago she completely stopped talking to me and we went from messaging a couple times a day to just nothing for a few days at best, naturally it hit a bit hard and I started to think that she wasn’t into me anymore or just had lost interest or something, but I gave her the benefit of the doubt and thought maybe she was busy or just didn’t have the time, however after a week or so of no contact I messaged her asking if she had lost interest and that its fine if she did, I would just rather she tell me than just ghost me. She text back later that day saying she was really sorry and that work had just been really bad, and things improved a lot and we started texting like we used to again, For a few days,before she went straight back to barely responding again. Right now I don’t know what to think tbh a part of me feels she’s still interested in me still, the other just thinks that she’s moved on. I’m kinda stressed out a bit, I really want to work as she seemed really nice and our chemistry was amazing,but I’m scared she’s either lost interest or playing me somehow. I don’t want to feel like I’m constantly pushing for something if the other person isnt doing the same. Any advice would be appreciated. TLDR- me this girl stopped responding and I’m not sure if she’s still into me.
