Confusion Ig?

2 days ago I had my debs, its not prom! but it fits into the same category (where u wear like a suit or a dress and dance, but u get drunk in it. shit like that). Now I'm not looking for sympathy but advice? idk I kinda have an idea what I wanna do. Anyway..

I went there with a best friend of mine. One thing I noticed is that my other "friends" barely spoke to me on the bus ride there, they only spoke when I started the conversation. Once we got to the venue we split up and through out the evening I HAVE NOT HEARD FROM THEM AT ALL! They fr hung out more with people who they shit talked for the whole school year.

Before I continue, or anyone asks me ig, I have never done ANYTHING to them. Haven't been mean to them (besides like having a mess), never shit talked them, NOTHING. 

I'm not gonna name drop incase they get onto spacehey, but to make it easier for me and for yous imma give them a fake name.

I have known Katie (fake name) since I was in 4th class of primary school (4th grade), even a bit longer than that cause we were neighbors. Now she did tell before that she found me annoying for the first year, until she realized I was alright, so we became best friends in our 1st year of secondary school (7th grade). Couple of years pass by and in 5th year (11th grade) we meet Jane and Sean (fake names). It was grand at first, we all got along well, messed around, hung out all of that normal friend shit. Now Ik this might sound harsh, but I do blame Jane, overtime I noticed that Jane would QUITE LITERALLY point at me behind my back with Sean and laugh WHILE I WAS PRESENT, we would always joke around saying that Jane is a instigator. Well its not a joke, cause once she started finding me annoying, the other 2 hopped on the "lets start thinking Erika is weird and annoying band wagon", and that's when it all started. Jane would tell me to "shut up" and if I kept talking, she would make and annoyed/ disgusted at Maria and Sean. The one thing that really pissed me off is that Katie is mad two faced. She would act normal around me like we were since 4th class (4th grade) and once she was around her boyfriend, Jane and Sean she would start acting that everything I say is weird. 

Fast-forward to our graduation, we still all kept in touch, and it was kinda normal. So I thought that everything that happened in school was them actually messing. So then we went to Greece for our Graduation trip, once again all normal, hell I even comforted my friend, cause before the trip because her boyfriend and her boyfriends mam were being absolute bitches (she was crying because of how stressed out ur woman was for this trip). Anyway when we came back from the trip and we talked for like 1 more month and then that's it. Radio silence. I would try to get them to hang out or talk more, but all I got were dry ass responses. So I stropped texting overall.

Now that I explained pretty much everything. I will come back to what I originally wanted to talk/ question about. 

1 day after the debs I seen a tiktok that hit me real hard. It was a video that said "And suddenly I stopped reaching out first and haven't heard from them since", and I realized that is fr what happened to me.

Like I said I'm not looking for sympathy, I just wanna know what I should do. I haven't blocked them or left any gc's or dropped them overall as friends, Katie's and Sean's birthdays are coming up and I wanna see if they will even bother to invite me to them, I wanna give them the benefit of the doubt by seeing if they'll even want to invite me, because I have a hunch that they have been going out to pubs or anywhere without me with the reposts that I have been seeing from Katie's tiktok. I know it sounds selfish, but I just wanna see if I'm being dramatic or overthinking things, or if my gut feeling is right.

So my two questions are;

1. If I should just drop them and leave them and pretty much block them on everything

or

2.If I'm somewhere in the wrong and if I did anything wrong, and should talk it out with them.

I will say this once again im not looking for sympathy, I'm just confused and need to see this from someone else's pov. (this fr sounds like an "am I the asshole?" reddit post)
