23M 23F Can someone please explain what's exactly going on and how do I get out of this situation?

Met a girl online. Initially I had no interest in her, I would just solve her doubts and move on. She started finding common personal topics to chat. Even i started answering it and eventually we started chatting a lot. But I had a hell lot of busy schedule so I was never able to message her first. She would everyday without fail message me daily to start the conversation. She even started sending flirty text and audio messages, and sometimes a pic of her doing chores, gym, etc. She would also share some personal stories of her and I would also reciprocate to all of her activities.

Eventually we met through a common get together after 3-4 months of chatting and after that she herself took the initiative to plan our 1:1 meetings. We met thrice back to back over course of 3 weeks, all outings planned by her. She would also make sure if I get angry for some mistakes she did or some lies i find, she would try to make up for that. Eventually I started liking her because of her behavior i.e. her caring and efforts taking nature. Also during our meetings, she would get extremely touchy and take pics while hugging me, placing her cheeks on my hand during a night trail, etc.

During our last and final meeting, I accidentally came to know about some of her lies like she mentioning I've never been in a relationship but I came to know about one she had in the past. She mentioning i dont go with male best friends out much, but her insta spam acc had 15 followers out of which 11 were boys and she had exactly 11 pending dms in insta app. She would always post on her spam acc her pics with her male friends but without face, just subtle posts like with hands or shoes, etc.

Ignoring all of her lies, i asked her if she wants to take this friendship a step further because we used to chat a lot everyday and also make efforts to meet every week. So it consumes a hell lot of time and efforts on both of our ends. I told her that since we both our going to join professional courses, it would be very difficult to take out time so if we want to continue further, it should be something meaningful. It's not an obligation for you to say YES/NO but if you say NO, we would have to decrease our chat intensity, frequency and day to day updates since normal friends dont do this thing.

She started giving some reasons like youre multi talented, you aced your exams as well as sports but idk whether I'll be able to do it. Then she said my college is in different city (~180km) so idk how exactly this LDR will work. Also she asked whether youre a date to marry guy or just for fun. I said date to marry and then she kind of turned off. Lastly she said youre kind of extreme personality. If you ever found a lie/mistakes done by me you will again get angry and stuff. So i asked her its a no right? She was just not ready to answer and finally I asked her just say yes or no and she said no. Then I said OK. Now after returning back home she keeps texting me flirty msg everyday, keeps sending romantic reels even though I explicitly mentioned I won't be able to reciprocate since I got a hectic schedule.

What's exactly going on over here can someone explain please?
