Is she still a friend?

The betrayal I feel right now, I swear...

Would you consider someone who constantly ignores you, even if you know each other for years, a friend? I know it's not on purpose but I already talked to her about this long ago and she promised not doing it again. It didn't last. I tried to endured it as much as I could, but this last thing...

We're both fans of this big group which has a concert movie on cinemas right now. I already watched it but didn't enjoyed it at all due to crazy screaming fangirls, so when new dates came out I wanted to go see it again, this time with her, because, I can't remember exactly why, she couldn't go last time, so I went alone. After the screening, I told her my experience, the annoyance that I had, and she agreed with me. But guess what? She didn't see any of my last messages to try and go with her to a new screening, but she went today and said she was upset because nobody screamed and singed. WHAT THE ACTUAL FUCK?! I sarcastically responded to that, saying that was a relief that I didn't go with her then. Maybe I was harsh, but I don't regret it. Perhaps I will in a future, but right now I'm actually really hurt. She did so many things for me, she's really kind and everything, but this really hurted me. If anything, I would regret something thinking about those things, but I considered that so many times before.

Maybe this would sound childish, but I kind of had enough. I have the right to be annoyed and hurted for whatever my heart feels attacked by, and the right to express it how I want. I might deal with the consequences later, but if it was worth the relief of letting out what I had knotted in my chest for so long, so be it.

PD: This is not the first time she does something like this. She once FORGOT I was going to her house. She told me to tell her when I would catch the bus so she will wait for me at the bus stop, because it was the first time I was going there. I texted her. Didn't have an answer. I arrived. She wasn't there. I called her. Didn't pick up. I called her mom and it was her who picked up telling me she forgot. A little bit of history so you know why I feel how I feel.
