AITAH for calling my bestfriend childish and immature?
For context, I'm 22F so is she, my bestfriend stopped posting me on her Instagram after posting me twice and having lots of her male friends hit on me and ask for my number. How did I know? She told me when it happened and sent me screenshots. She was annoyed and replied to all of them that I was taken (even though I'm single) I was surprised she did that but I just moved on and didn't make a big deal out of it because I didn't care about the compliments anyway. And now she never posts me, not even a story for my birthday. However, yesterday she texted me telling me why I never reshare posts/ stories except my sister's and ignore everyone else (it was my birthday, my sister posted a story for me and I reposted it, it's our ritual I never repost except my sister and I'm not even active on Instagram) so I told her she has no right to even bring it up since she hasn't posted me once in the past 2 years or so. So wtf is she even going on about? She said "I used to post you and you didn't care to repost so I stopped". I told her "I thought you said you didn't care about these minor things? And let's be real - you only stopped posting me after I was getting all the attention not because I stopped reposting especially if I never started reposting anyway". She kept denying it, even denied the fact that she told them I was taken at the time and she called ME self centered. I just told her she's too childish and immature, and that it's not like I'm singling her out, I never repost anybody except my sister always and everybody knows this and doesn't mind.
I didn't bother to check the last msgs she sent me but I'm sure she's furious about it so AITAH for going off on her?
