Am I the asshole?

Hi, I female(14) and my two best friends Female (13) are no longer friends due to an argument between one my best friends. so I had told ebony  that I got converses from my parents because I have owned the same shoes for 3 years now.  She says 'omg really I just got $300 for Christmas' I reply 'thats great!' She says 'send me a picture of your shoes because I'm getting converses too and I want to match with you' I say 'hey I don't want to sound like an asshole but I don't want to match shoes with you due to getting them for the first time and I've always wanted them' she replied 'yeah that's totally fine' she kept on asking me from then on everyday every hour. I post a tiktok doing a dance with my new shoes on thinking she wouldn't care...
She messages me as soon as it's post saying 'omfg bro I'm getting the exact same shoes as you' my heart broke I reply ' your joking right' 'no!' I'm sitting there thinking great.
I asked her 'hey I know you getting the same shoes as me but can you maybe get another pair because these are my dream shoes and for me it's not fair that I get them and now you getting them...' she reply's with big paragraphs calling me names saying  'get over yourself and not everything evolves around you! I want want them and I'm getting them' I say 'ok I was just trying to ask but it's fine have a good night x' she replies ' yeah whatever you've just ruined it so THANKS' I say ' I'm sorry but you'd know how it feel if I did the same..' she ignores me I say to myself it's ok she'll talk tomorrow and it'll be fine than a message pops up it my other best friend... I will show the messages cause I can't be stuff writing rn:

so there's a lot of juicy tea so you guys might be here for a while....
