Is there a possibility for coming back from and regaining attraction after 'beta-behavior'? How do I stay in a girl's spotlight while at the same time being distant and seeming active?

My situation is this; a girl I actively want to LTR has been sending mixed signals.

At first she was all for it, but somewhere along the way I must've botched it tremendously. After a while I started noticing that she started partying a lot more and hanging out with other guys, I confronted her, feeling a bit. In an obviously disguised as assertive way, I told her to either settle or call it quits. She got very angry and upset at me for this. We discuss this for some time, and in the end she insists and and hits me with: "But we were never dating?" so I told her "Then there is nothing" and left to go home without a another word. She sent me a text hours after I had left, throwing soft insults at me and just generally being upset. I soft nexted her for 5 days but never got a word back. Impatience and frustration lead me to texting first, acting like the next never happened, however it was received well, fortunately. That is, until I began talking about it again. It started off with a seemingly promising build-up (she seemed flustered about the idea this time? She was showing obvious signs of attraction, indecisiveness and maybe answers) but it ultimately went to shambles, with her responding emotionally saying she was heartbroken by what I said and my refusal to interact with her if she does not want a C(losed)LTR now. She said she wants it at a later point, and that she just wants to do whatever for now. She asked me to stay friends until she wanted a relationship again. I responded with a short text explaining my reasoning and making my next move somewhat ambiguous but slightly implying that I will stop interaction. After taking 2 hours she responded with "I don't want it with you now", I reply with "Alright", to which she replied "perfect",

which brings us to now. I re-initiated the soft-next, which this is the the 4th day of. I am clueless on how to proceed. I broke it three separate times on the second day. She sent me a text asking why I was taking so long to respond. To which I replied "Haven't had time"'.
She essentially ignored it, but replied nearly instantly happily telling me about what she was up to. Same day, some hours later I commented on it, which she ignored entirely. She sent a text back, again, instantly, again, casually telling me about what she had done that day.

In the past she has always been extremely into me, being mostly blind/forgiving toward the beta-behaviors, although this has definitely waned a little bit over time I've always tried to keep my frame in the "unfocused on her, very active life" zone, but get the feeling I either overdo it (extreme disinterest), and break it too quickly and start feeling needy, so what's the goldilock zone here? Even now, she always responds to everything instantly, and clearly there is interest and she wants to talk, I'm just not sure how to best utilize this to turn this into an LTR.

Is there a way to resolve/rebuild this? Severe case of oneitis, but I want to give it my best shot before I put it down completely.

Best advice pertaining to the above mentioned situation, as well as the questions posed in the opening of this post? Thank you.
