aitah for being upset at my ex-friend?

my ex-bestfriend blocked me. i started to grow a dislike towards her because of her opinion on many things. she called wonyoung (a k-pop idol) a desperate sl-t, disrespectful, a pick me, an attention seeker and she doesn't want her favourite idol (bias) to get along with her. i really found it weird but i let it slide because she was my friend. then she said that they're a "better" and "prettier" fan than another fan who stans the same idol. but this isn't a competition, right? she always judged people but i let it slide again (which i shouldn't have done).

she always talked about wanting to meet me one day and when our favourite group announced a world tour in her country, we were both excited. it was her who said she'd pick me up from the airport and show me around the city if i'm visting, which i thought was very nice of her. we thought we'd get tickets for the concert on the same day to meet up, but the ticketing process was too exhausting and i couldn't secure a vip ticket (she got vip tickets to go with her friend). but then the group's agency added an additional show and i was able to get a vip ticket. she didn't sound happy when i told her i got a vip ticket and kept talking about how the ticket i had isn't "worth it" because you wouldn't get any interactions. i wanted to tell her that not everyone is hungry for an interaction (she always talks about how she wants her bias to notice her someday) but i held back my tongue because she had her own backstories.

her opinion on how the ticket i had isn't worth it didn't stop until the day before the concert. when she brought it up the first time, i said i'd rather sit somewhere and enjoy the concert than standing for hours while getting pushed by other fans, and that i'm not looking for an interaction with the members because i'm more than happy to watch them perform in real life. she said "yes", "right", "true", but she never stopped. she brought it up again and i had to tell her again that i'd be fine with my ticket. (note that i had a seated ticket while she had a standing ticket)

last week she texted me saying she can't meet me because she has plans with her other friend. i was upset because i wouldn't be flying to her country and attend a concert if it wasn't for her, and she also sounded so excited about meeting me. but i didn't say anything and said that it was okay.

then when i made a nameboard to bring to the concert, i showed it to her and she said "i would laugh at you and judge you with my bestfriend if you weren't my friend". she could've told me to remove or add something to make it look better but her choice of words hurt me. i didn't bring the nameboard to the concert.

she bought me a necklace a month ago to give me when we meet up, and i was more than happy that she thought of buying me something. but since she cancelled our plans, she put on a story asking if someone likes gold jewellery, what i didn't knew was that she was asking the necklace she bought for me so she could give it to someone else. but i already texted her saying that i don't like gold. then she replied to me saying "oh that's why i'm giving it to someone else cause you don't like gold anyways", which upset me. i prefer to wear silver more than gold but i was still happy with what she got me and that she got me something to begin with, and complaining about it is the shittiest thing one could ever do when someone spent their money and was sweet enough to buy you something, that was what i thought. but the way she said it upset me and i found it disrespectful that she wants to give away the gift she bought for someone to a different person. it would've been fine if she didn't mention about giving it away because i was too occupied to think about her gift. but i don't think anyone should give away a gift like that to someone else. anyone would be upset if you give the gift you bought for them to someone else or if you give someone a gift telling them that they got it for someone else but they're not giving it to them anymore. i said yes please because it's her own money and it's decision to choose what she should do with it (if it was me, i'd either keep the gift to myself or give it away to someone else without letting them know). but she wasn't happy about it and later put a story saying "this one online friend pmo so much". i thought she was talking about a different person she mentioned to me about a few weeks back and when i asked her if it's her other online friend, she said "idk" and that's how i found out it's about me. i asked her if i did something wrong because i was completely clueless about what was wrong but she left me on read. later when i texted her again she said "don't you think it's rude of you?" referring to my yes please. i replied back to her saying that don't she thinks it's rude of her to give away a gift you bought for someone to a different person. i was being calm and respectful towards her, i didn't want us to get into an argument. but she replied "well it's not like we're meeting anyways do you think i'd keep the necklace till you come here again? absolutely not", "plus you don't like gold you wouldn't even bother to wear it" which sounds very rude, but i was still trying to be nice to her. i tried explaining her that i love the gift she bought for me and the fact that she wanted to gift me something, and that i would never complain about what someone's gifting me when they spent their money and time on it and that i would've definitely wore it. she said that "i don't care" by the way i told her to go ahead giving the gift to someone else. i said i do care and i ended up apologising for nothing. but she never accepted the fact that she was being rude and disrespectful. all i got was a "sorry" when i apologized to her multiple times. i told her that i'd prefer her to be honest with me in the future if she has any problems with me so we could sort it out instead of her putting a story and making me guess who it was about. but she said "oh but my story my rules but okay ig". i said okay sure but at least make sure i don't see it? anyone would be upset if they see themselves being talked about negatively in someone's story. she said "i wanted my other friends to know that i'm pissed", "and they don't know that i'm talking about you". i told her that it's not about what others think but it's about what i think. in the end she asked if we could accept that both are at fault and that this was a misunderstanding and move on. i agreed and tried to cheer up the mood, but her way of texting me was very dry and i gave up.

i didn't text her a lot after that argument and i realised i shouldn't continue to be respectful to someone who is disrespectful to me. i stopped sending them the posts they never saw and stopped texting them good morning/good night. she didn't know i was already in her country at the time and neither did she seem to care when i told her.

we were talking about the concert i'm going to the following day and she once again brought up how my ticket isn't "worth it", she even sent me a few screenshots of someone explaining about it. i told her again that i don't want to stand for hours. but my view was so good at the concert, i was able to see everything perfectly and i was so close to the stage, the members kept coming to our side too. later that night when i told her about how it was so worth it, she didn't sound happy. i told her how she needs to be in the barricade at her pen so she could get the interaction she wants so bad because pen a and b was much bigger and ends at the extended stage, while pen c and d (the pen she was in) starts after the extended stage and people who has cat 1 standing tickets were mixed among the vips. i believe she was quite upset about it (so was i when she kept bringing up about how vip seated isn't worth it), but i was still hoping she'd be able to see them properly. but when i checked her account to see how the concert was, i was already blocked by her. i'm not affected by it because some of my friends told me to cut her off after i heard her so-called "opinion" about wonyoung. and i was sure that i have to cut her off someday after the argument we had.

i checked her profile earlier today and i was right, they indeed did not have a good view nor did they get any interactions.
