Is my friend group slowly excluding me?

I don't know if I'm imagining it or if it's actually happening. It's not obvious. Nobody has said anything to my face. But I've been noticing things. Hangouts I wasn't invited to. Plans being made in front of me that I wasn't included in. Conversations that stopped when I walked over. Nothing I can point to and say that's the moment it changed. Just a slow steady feeling that something is different and I can't tell if it's real or if I'm just being paranoid. I started thinking about whether I'd done something to cause it or whether it had nothing to do with me at all. I also thought about why not knowing was almost harder than knowing. When something is slow and quiet you spend most of your energy doubting yourself instead of actually dealing with what might be happening. I couldn't figure out if I should say something, do something, or just wait and see. I realized I'd been so focused on figuring out what I did wrong that I hadn't stopped to ask whether these were actually people I wanted to fight to stay close to. The question wasn't just is this happening. It was whether I actually wanted to fix it or whether I'd been holding onto something that had already run its course. Talking it through helped me see that I'd been spending all my energy chasing something that wasn't chasing me back. We agreed the best next step was simple. Stop going out of my way for people who weren't going out of their way for me. Not a confrontation, not a dramatic exit. Just quietly stop chasing it and see what was actually still there without the effort. It was going to feel like giving up at first and I knew that. But the alternative was keep shrinking myself trying to hold onto something that might have already let go of me.
