I'm kinda lost about what to do in this situation?

in the current stage of my life I'm looking for a partner. I've met a girl who aligns with my priorities. when we're together we have really good vibes and we can talk on a deep level without much tension but when I asked her on a date she said that there's someone that she likes and is trying to make things work with him and that she sees me as a big brother and bla bla. the thing is I want her, so for a few days I kept giving her attention everyday I'd call she wouldn't answer but send me a message instantly with an excuse , she always replies to my messages instantly no games nothing. for 4 days I've completely dropped my ego and male logic just to give her attention that I'm sure no one else is giving her that also with things being more tense and both of us thinking about that. I'd call , she wouldn't answer the call but reply with a message so I'd stay quiet , next day same happens but we have a text back and forth , 4th day she gave me a colder response so I gave her a warming text. then on the 5th day she answers the call , we talk for a good time , she was very feminine with me she was warm and loving but then she brought out the word "bestie" so I changed my vibe with her and said "we're not friends you can call it whatever it's but I'd leave If you put me in the "friend" zone" then we changed topics kept talking and then went to sleep, the next day I wake up send her a text "I had fun hanging out together yesterday" and then she replied "it was fun" since that it has been few days without texting or talking. at this point I'm kinda lost and I don't know what to do. My logical way would be just ignore her If she comes she comes If not then you already move on. What should I do to get her? I really want her, I've been in relationships before and I've game and stuff going on for me in my life, this isn't my first love this isn't a rebound. I just love her simple as that.

14 days have passed without talking to each other , She texted me on day 14 to "Check up" on me. I said I'm fine and asked how's she , said "I'm fine but bla bla" after two hours I called she didn't reply and texted me with an excuse. the next day I called her she was about to do the same so I texted this is kinda important then called , she answered I asked her If she was fine or If anything have happened she insisted that she's really fine 3 times then she said "We're friends so.."

"I was checking on you" then I said "Did I hurt you before in any form?" she said "NNoo" then I said "then why you're not putting up with my boundaries you spent 14 days without talking to me I don't befriend women and I told you that" then she said "I understand" then I said "This is going to be toxic and you'll hurt me and I'll hurt you so we should leave it at that good luck to you bye"

I have 0 regrets moving on. I lost someone who didn't love me but she lost someone who really loved her
