Some Background
I'm a college student, currently a junior. Part of a large-ish diverse group of friends, split across two six person suites. I've been in this group and friends with these people, for a little over 2 years now.
Obviously the entire group doesn't hang out all the time, everyone has different schedules, workloads, lives, etc. But often smaller sets of people hang out, and sometimes larger meetups.
The Problem
I noticed this semester that I wasn't really seeing anyone/hanging out with anyone this semester, and just thought it was because everyone was busy and we we're all only occasionally meeting up.
Well it turns out that a lot of my other friends were meeting up several times a week to hang out, eat, and do stuff, including at night. At first I was a little jealous because I was, for some reason not invited to these, but marked it off as being with just a few select people. Then it turns out that it is quite a bit more people than they let on who are actively getting together/meeting up.
I also noticed that it is only me initiating online conversations, so I just stopped being the one to put in all the effort, and what do you know, nobody messages me.
How do I react to this?
I feel extremely hurt by this, and my first thoughts are that maybe I was an asshole? Offputting? Or something else going on that they not only don't invite me to anything, but kind of cover-up or go out of their way to minimize or not make a big deal out of these things (as well as the fact that nobody is messaging me).
I asked a few people and told them to be brutally honest with me if there was some issue with me/if I was a jerk, etc. And they just said that it wasn't me, it was the group being bad friends, but i'm not really convinced.
Sorry for the long post. I'm not sure what to do, how to handle this, as I'm feeling extremely lonely while theoretically surrounded by people.
To help paint the picture a bit better, earlier in the semester a bunch of them were organizing some massive day-out in the town nearby or something, that was supposed to be a great day of doing some things in town, and drinking and hanging out. When I heard about this all they said was that it was invite only. Later, when I brought it up (they were talking about it) they just ignored me and changed the subject. So realizing I wasn't going to be invited, I planned to go to a conference that weekend. Of course, the day before the weekend, they find out in going off to a conference and then say that I'm missing this event and that I should go, knowing full well that I can't go, and that I was not invited in the first place. I'm pretty sure they just did this so they could act/say I was invited in the first place, knowing full well I never actually was.
