AITAH for asking out a friend?

So I 14 F, have a friend (also 14 F), I'm gonna call her lilith, and I've had a crush on her since year 7, but in about the end of year 7 I dated one of my other friends, I'll call her Alice, and the relationship was good, it just lacked affection because she wasn't into that stuff, and I dated her to get rid of my crush on lilith, but when we broke up after 2 years my crush for lilith came back full force and I started to hint to her by tagging her in "us" videos and compliment videos, she eventually figured out and she texted me a long paragraph saying she was fine with it if I was, and I did say that I liked her, she liked me back, everything was good for that day, but then on a Saturday not long after she said she wasn't ready for a relationship, I said I was fine with it and we arranged to hang out and talk about it, but I got really sick during the day and I got my period, so I was in bed for a whole week, and I missed the hangout day, I was too nervous to ask her again so I didn't, and after a few months she started to distance herself, I tried texting her about it over the 2 week April holiday, she was too busy and then she started to full on rubber me, I tried to text her one final time but she didn't respond at all, and then she blocked me on tik tok, I wasn't pissed, just confused, and then another friend, I'll call her Lucy, unfriended me on Snapchat, I'm fine if they want space but they could atleast tell me what went wrong and what I can do to fix it. I need advice on what to do and if I was the jerk because I'm not good with confrontations, I don't like to pester people if they want space but I feel like I did something wrong and I don't know how to approach the situation about it because I'm scared she'll drop me over it and I'm already in a bad enough state as it is and I have no idea on what to do because she gave me mixed signals (cuddling, getting too close to me and glancing at me alot) I don't know if it was platonic because I'm horrible at that stuff and I just want to sort it all before I actually lose them
