I made a diff acc cuz some friends know my main and I cant really talk to anyone about this.

I have a childhood friend, and we both know things about each other that we dont generally share to others.

Then just few months ago we started talking more than usual and it led to them asking if we can be friends with benefits. It didn't last long until complications started. I started asking for reassurance and they mistook it as something that borders the line between friends and partner.

Eventually we agreed to stop because things are getting out of hand. We decided to just remain friends. However, after that things changed badly. We no longer talk even if I reach out. I got the sense that Im being avoided. So here I am regretting what happened cuz I feel like I just lost a friend and I really shouldn't have agreed in the first place. I feel upset and stupid.

Using a new account because friends know my main one.

We're long-term friends who don't talk often. We just started interacting regularly, and after a while, we agreed to try B&D since we both knew we'd been into it for many years. We also agreed to remain strictly platonic. I'm a sub.
It was going great for like a month until I asked for reassurance. He mistook it for us crossing the line from just friends to a romantic relationship. That basically opened a can of worms, and we agreed to end things.
Now, he barely interacts with me after those events. He mentioned he needs to undergo minor ear surgery, but beyond that, there's no further interaction. I understand health comes first, but I can't help but think that I did something wrong. I'm starting to wonder if the only reason we were hanging out is because of that and not cuz we're friends. So, how am I supposed to navigate this situation?
