Friends watched Iron lung w/o me

I just mostly wanted to just be allowed to let this out without any chance that my friends or anyone else sees this, since I harbour no malice towards any of them.

Last week monday, one of my friends asked in our group chat kinda jokingly if anyone wanted to watch iron lung by sending just a pic of the movie schedule in our local cinema, I made the suggestion serious and wrote "let's all go watch it"

Then we met up over lunch all of us on the friday that week and while the others were doing something else I brought up the subject to him again about all of us finding a time, I wasnt sure if the others were interested cuz they didnt reply in our groupchat hence why I didnt wait till the others got back, but I was still definitely hoping theyd come with because its more fun with more ppl.

We're in uni and all have different courses to getting things to time well is hard, and he said im free this Saturday or after Wednesday. Since I was busy on Saturday I said im free next Friday. The conversation eventually went elsewhere without concrete plans.

On the Sunday another friend wrote in the groupchat "were we planning on going to see iron lung?" And I responded "yeah me and X were talking about going on Friday maybe?" And the I got no response to that.

Then I found out through a picture I got from a friend outside this groupchat that they all decided to go on the Monday while i was working (they didnt know that i was working ofc so its not like they deliberately planned it so that i wouldnt be able to come) it was probably a spur of the moment thing that happened during a planned meet up that I was invited to but obv couldn't come to cuz I was working.

But it kinda hurt to have been very active in the convos about watching the movie and having everyone go see it without me, im upset at the situation and that I didnt get to go see the movie, im not upset at my friends. I consoled myself by buying a game instead lmao.
