Long story short ive a group of 8 friends from school that ive remained close to for the past twenty years. Over time we've tried to have regular meet ups, we've all had kids and have arranged playdates and birthday parties over the years. As the kids have gotten older and made their own friends in school etc the meet ups have got less and less. Out of the 8 im particularly close to 3 and we meet up for adult only times, the others seem to have their own group and have met up etc. ive noticed for the last year or two when I post in the group chat the other 4 rarely respond but yet when one of them post we all 8 write something back. This became apparent with first day back to school photos, some pictures got a lot of comments mine just from my close 3. Recently there's been talks of an expensive trip away and I honestly dont feel I want to go with the large group as I dont feel close to them. Ive checked and the last time ive received an individual text from them that wasn't prompted by me messaging them first was over a year ago for some. Im at the stage were I just feel like they aren't really my friends and im just there for numbers in the group, AIBU to just cut them out and focus on my real friendships? Should I just make excuses for the big trip and then get a smaller one organised with the 3 close friends?
