hello, i know im abit late to this post but i have expedited the same exact things, im also currently in college and i had a group of friends who was in the same course as me, me and one of the girls in the group have been friends ever since i joined her school in year 10, and the rest we all became friends when college started, recently they have all just removed me and removed me from our group chat, the same girl who was my first friend in year 10 posted a tiktok clearly aiming it at me, and soon removed it when id seen it, however i haven’t done anything? If you ever need to talk about it im always up to listen…. as long as we know we haven’t done anything then we dont need to feel excluded, we dont need to message them because they never felt the need to message us about the issue, we are being mature and not giving them an argument that they crave. they’re all clearly jealous or scared of you, believe me the whole group would not have said they all dont like you, it will be the “group leader” and everyone else has just followed along. however, like i said we have both experienced the same despite us reacting differently about it and i know we will both be fine and friends will just come into our life when needed. If they leave then they was clearly just friends to teach us a lesson in life. you are an amazing individual and anyone would be proud to have you in their life ❣️❣️
