it probably would have been ~ideal~ to bring it up after the birthday or just quietly not invite her to the next outing if it’s a pattern of behavior, but it’s understandable to be annoyed and react in the moment. i’m going to say soft NTA leaning toward NAH depending on the context of the friendship, what else could be upsetting her, whom else she could be busy replying to, etc. for example, my dad passed away about a month after my 19th, and i was def totally checked out while he was sick.
Ty for the feedback. For clarity, she wasn’t upset at anything and she regularly gets me bday gifts. I pay for all of her gifts and I’m broke her parents pays for mine. She was on her phone either taking selfies or texting her online bf and after she posted the selfies and the movie theatre but she didn’t caption it or mention me. She gets me good gifts on my bday but this year she didn’t gift me.I still gifted her to show her I care but hurts being unappreciated
