Yes. This happened to me. I thought we were friends. Everything was fine. And then one day I get that and the friendship is over.
When did things start going wrong? I have no idea.
What did I actually do or say? I have no idea.
So now I get to guess. What is it about me that would make a person feel that way? Now I am paranoid that everything I say or do is upsetting or offending someone. I'm often afraid to share my opinion or thoughts about something. And when I do I feel like I need to preface it with "this is just how I do it. I don't care how you do it. I'm not judging you." And I am sure that can be kind of annoying.
This person thought they were "helping" me by telling me that I made them feel that way... But really... what does it actually tell me? Nothing. Absolutely nothing. And how do you work on being a better person when no one will ever explain to you where you go wrong? It's tough.
But I just wanted to say that I think that was a really crap way of dealing with things. I feel better now that I got that out.
