hi there, I am currently in college. I have had this group of friends for a while, but I have noticed that they are getting closer to each other. They started to hang out and make plans without me. I didn't want to be upset over this, as it seems rather childish, but it has gotten to me unconsciously. I did notice them talking about their plans in front of me a couple of times, and it makes me upset. I don't think they have any ill intentions, but I do feel hurt whenever it happens.
