AITA for being annoyed/frustrated?

Hello everyone, I’m a bit lost on this one because in my opinion friends shouldn’t do that to one another. So, long story, me and my friend group really love BTS and I was dying with excitement when we found out they would come to Belgium. I thought since we like them then we should go together to the concert. But then one day I was calling with one of my friends on discord bc she wanted to watch me play a game, then out of nowhere she starts texting our other friend about the concert I was like “maybe she’s keeping her up to date” then I went on mute bc I needed to open the door to get my mail and when I came back on call they bought their tickets behind my back. I was genuinely confused and sad because why would they do that if we were supposed to go together???

Anyway, I just stopped asking or even thinking about the concert because if they didn’t invite me too I wouldn’t ask if I’m not welcome right? So now it’s only like a week away the concert and one of my friends is starting to literally tweak in group chat about the concert and tbh everytime she brings it up it makes me a bit left out.

And before anyone asks if I addressed the issue, yes I did. She was talking few times about FOMO with other things related to music and mutual interest and I literally told her “Now you know how I feel about the bts concert” and also she’s the only one talking about it, our other friend is more subtle about it.

So my question is, do I not have a right to feel annoyed with her? Do I call her out on the behaviour about it?
