How do I get over a girl that clearly doesn’t like me and lead me on?

Backstory: I am a freshman in University currently and I started in September of this year. However, before I started, I met this girl through an Instagram group chat of all the freshman entering the University. We got to know each other quite well, and in fact we would call and talk to each other for hours before even meeting each other in University. I started to grow feelings for her in the last one month, and ever since University has started, we have hung out at least 3-4 times a week, for hours on end. It would always be a mutual thing, and sometimes it would either be going to the mall, shopping, lunch, bubble tea, etc. While I never asked this girl on a date officially or even told her that I liked her, I’m starting become confused in if she likes me back. She consistently invites me to hang out, asks me everyday if I’m doing okay, talks for hours with me in classes and also after classes, and basically gives me all of her attention. But, I swear, this girl is giving me the most mixed signals. I have written them in bullet points down below.

1. In the past, she has stated how she likes guys with long hair (I have short hair, and my friends think she is trying to make me jealous or smth)
2. Literally yesterday, she asks me how to ask a guy out, and states that she has a crush on this guy (at first I was like damn, she’s not into me, but when I actually give her good advice on asking a guy out, she literally responds very dry saying “Okay” or “right” and then says she doesn’t want to ask this guy out (which my friends think is her trying to fake that she likes a guy to play mind games on me so I can confess I like her or smth..?). And 3 days ago, for the first time in a while, we don’t see each other, and she posts on her close friends story stating “oh I dressed really nice today to see my crush but I didn’t get to see him” (which is legit making me wonder if its a coincidence or if it really is another guy). And then yesterday, she posts on her close friends this tiktok with the caption “when he doesn’t react to the story I specifically posted for him.”
3. She always likes to go on my phone and see who I am texting and does playful banter with me ALL the time
4. Literally does so much shit for me (before exams, she will write notes for me, do a bunch of little stuff
5. Everytime I drop her off back at her place, she always wants to talk with me in my car for a really long time before leaving, and usually its me asking her to leave as I have to go.
6. She hangs out with me and talks to me constantly, whenever I’m down she always will be there for m. For instance, I was in the hospital and she would ask me for updates every 45 minutes. However, I understand that she could just see me as a really close friend.

With all this in mind, this whole crush thing and whether or not she likes me or not is what is confusing me. It seems that there aren’t even any coincidences anymore, as the stories she’s telling about her “crush” seem to be real. Because of this, how do I move on? Should I just tell her I don’t want to be friends and leave it at that?
