Hey everyone!

I'm mostly confused about this and wanted to maybe get some other perspectives on this.

I've been watching a relatively small streamer for a few months now and the chat feels like a small family, everyone knows each other and talks among them and with the streamer. Now a woman who always used to be there and talked very friendly with everyone hasn't been there for a few weeks now and I kind of missed her, so I added her as a friend on Twitch which she accepted. Then the dialogue went as follows, I'm copying my messages and transcribing hers as I assume she wouldn't want me to copy them:

Me: Hey! Haven't seen you around in a while, all good with you?

Her: Hey! I'm perfect, how about you?

Me: That's good to hear! I'm getting done with college right now, only one more exam to go! Did you find some new streamers? I was surprised to not see you in [streamer]'s chat anymore

Her: Says she'd like to curse at me, asks my how I'm of the opinion that this is an acceptable question, how it's way too personal as we've only talked a few times, asks me why I care and to back off, says I should find someone else to talk about.

Me: I'm terribly sorry if I offended you by this, I was just sad to not see you in chat anymore and yes a bit curious and wanted to make conversation. I guess I crossed a border I didn't see, so I'll just back off then.

She had already deleted me from her friends list by then. If she felt like that was too personal, why did she add me in the first place? To be honest I was trying to take the high road here because my first thought was "wth is your problem?". I assume it might have something to do with her having an unpleasant exchange with [streamer] at some point, because he had mentioned something like that, so maybe I just struck a nerve.

However, AITA? I just don't see how any of this was inappropriate.
