I F23 removed my friend F20 over a misunderstanding

So I F23 and this friend F20 were friends for many years and we also were doing snapchat streaks and talked about multiple topics and also told stuff that I wouldn’t want others to know.

Now, there was this situation where she posted on her spam page (finsta) a screenshot from tiktok that there are ppl who talk badly about someone and I replied and said that another girl who we both know said that she was a bad person ( I already told her about that a year ago and have no contact to that person anymore ). She then removed me from her page and forgot my main acc and said sth like “don’t pmo, you were still friends with her then and only told me now?” in her story.

I saw the story and replied that I already told her about that and sent her screenshots of evidence that i told her about it a year ago when I told this friend about this situation.

Afterwards, I removed all of her accs from my social media (insta, tiktok etc) and only have her number still saved.

She still hasn’t responded yet and I will not double text her if she doesn’t respond to this message.

Does that seem immature from my perspective?
