@bobaballkookoo If I were in this situation, I would first try to address it directly and calmly. I’d approach one of them and ask, ‘Hey, I noticed things feel a bit different since I came back. Did I do something to upset anyone? If I did, I’d really like to understand.’ If they open up and it’s something I can address, I’d make the effort to fix it. But if they brush it off or keep acting distant, I’d stop wasting my energy trying to figure it out. I’d focus on my exercises and remind myself that I’m there to exercise. I’m there for my own growth not to please anyone.
If their behavior still affected too much, I might suggest to even consider switching to another place where it would feel more comfortable. People sometimes behave immaturely even as adults, and it’s not your job to overthink or fix their dynamics. Just remember why you started, focus on your goals, and let them deal with their own issues.
