All my so called friends forgot my birthday and didn't even remember it until my super sweet senior who was my roommate previously came to wish me the next day. I was in college internship and even my batchmates didn't remember it until then. (I had no issues with my batchmates not remembering since I was not really close with them - only sad about my close friends forgetting it) I kept waiting the previous night from 12a.m to 2a.m that they would surprise me just the same way that I and others did for everyone else's birthday in our friend group every year even if we had our exams or anything else during those days.

I always gave super thoughtful gifts they would have wanted or gave handmade gifts/cards every single year throughout our college years. But every year, I barely received a half hearted wish if that and gifts that were not at all relevant or my taste. Those gifts barely showed any effort or thought on their part.

I was deeply hurt that even though I thought of them as my close friends at the time - that didn't seem to be the case for them. I only got to know even later that they had a different WA group chat without me that they were all active in and chatting all the time - I'm assuming that was because I don't drink or smoke or date guys all the time like most of them were. I was never included in anything they all were doing and I could not even sit with them when they were hanging out since they would usually smoke and I get migraines due to the smell of it. I'm pretty okay that they could hardly be bothered to include me in their outings etc because I do understand that their interests are very different than mine and I'm an introvert anyway so its fine not having to go out all the time. I just thought that they would at least remember me on one day in the entire year.

I've cut off ties with most of them after that since i'm quite exhausted by trying to be friends with people who could not be the least bit bothered to remember that I even exist.

AITA for not letting this birthday situation go and don't want to be friends with them anymore?
