Whats it she trying to say?

This girl is my classmate,

she's got too many insecurities and is a really big overthinker just like me.she considered "her man having jealousy" as the love factor and finds it really hot

we've been texting eachother every single day since past 5 months every day every minute same energy between us,we never ignored eachother would reply in seconds without any hesitation

but by the end of January I started to realise that I was catching feelings for her and I shared it with her thinking sharing would help me and the feelings myt stop if the feelings weren't real(coz I didn't want to turn out to be the guy to ruin our friendship and I didn't really want any relationship with her)

But the thee feelings didn't stop so one night feb 16th ig i confessed her again abt the feelings and everything coz they were just growing more and told her that I accepted the fact that I like her and asked if she really likes me back but she didn't reply and was just repeating"idk what to say" and was giving mixed signals and asked me to find out if it was really love or just attraction I told her I would put BLUE song in my insta note if i find out that i love her.then later one night I forced her to say yes or no and she said she would post an insta note abt it (she posts "Blue song with a caption saying "I will write books about you think you in my heart but will never tell you") and said it was for me (i literally jumped in my room and was goddamn happy)

the next day after college she looked at me and gave me a smile but I got so frozen and turned my head out of shy but after clg I went to meet her and asked her if it was a yes then she denied it and she was like "you understood it wrong i didn't mean it that way" and she never said what she meant and started behaving weirdly

we are still close friends and we still talk close butt she still gives mixed signals and loves making me jealous by telling me fake stories with a guy in it(she makes up stories and herself shares them with me)just to make me jealous

ufff what should I do to get her I really love her a lot and put a lot of efforts, and we are so close now that a day without eachother we both really get cooked badly but she wouldnt say if she likes me back or not
