My best friend found out on Instagram two days ago that I'm going to a concert next week (this week) with my close friend. My close friend posted it and tagged me in it. They don't know each other well. My close friend and I have been listening to this band for a few months. She texted me angry saying, "Why didn't you tell me you were going to a concert next week?!"
She doesn't even know this band. I told her about it and she said, "No never heard of them." I told her there is still time to get tickets but buy them online. She is like, "Whatever! It's too late now! My own best friend didn't even tell me. Why don't you tell me anything anymore?! I invite you to places and you can't even do the same for me!" I was like, "You've never heard of them so how can you enjoy them? I'm sorry sis." She isn't responding. Wtf
I sent her the link where to get tickets. The concert is this Thursday.
My aunt said I should have at least told her and frankly I'm a bad friend for not telling her. Don't forget my other friends.
My mom said I did the same thing to my other friend (now ex friend) for not telling her about the party and I told her the last minute. My mom said bluntly I'm not being a good friend and I okay the victim too much and don't wanna see my own faults.
I was going to tell her!

First of all, it seems rather odd that you have this scale of "best" vs "close" friend. It also seems unusual that your best friend wouldn't know a close friend.

So, how do you distinguish the difference?

Are you a good friend? That's hard to answer.

It could be that your friend is being unreasonable. But, it also appears that you have had relationship issues like this with others.

It could be that you are not setting clear expectations in terms of what you expect from a friend and what you expect to give to a friend.

Do YOU think you're being a good friend? How would you react if your "best" friend did the same to you?
