There is no lengthy story behind this post, just feelings which I have contradictory meta-feelings towards. To put it bluntly pretty much all of my roommates friends are people that I have introduced them to. At the start of the year I went out of my way to add them to groupchats I was in and call them when I was going out. But ever since we moved in together in September there has been a consistent trend that after introducing them to friends, a while later (sometimes literally days) I find out they are hanging out together without me.

On one hand, people are completely free to make friends with whoever they want to, my inadvertent negative feelings towards this makes me feel like I'm a horrible human. At the same time, why does it ALWAYS have to be specifically my friends, and why does he have to deliberately exclude me in their plans?

It's so weird finding out that a group of your friends will be hanging out at your place while you are totally left out of the plans. Especially since I am quite introverted, so when I form a close friendship it's pretty special to me.

I'm having a difficult time reconciling this because my roommate is a very good friend yet I can't tell if this is done intentionally or not because it has happened so many times since September.

It's so stupid and immature to feel like my friends are being "stolen" from me, but I can't help but feel that way.

AITAH? I'm probably going to discuss this with a therapist as well to help sort through why I feel this way.
