Input: I assumed that everyone gets annoyed at their friends at some point, and a normal part of any relationship is venting to someone about the things a friend does that annoy them. I don't want to actually confront this person and say that these things annoy me because it's just a part of who they are and who am I to try and change them. I've told them to tone it down, asked them to do things differently but they won't because it's kind of just their personality. So basically, they piss me off sometimes and sometimes I like to just vent about stuff that annoys me. 

I met up with a friend for coffee and we were just talking about stuff, she was complaining about someone so I joined in. We had a rant, all was good, we went our separate ways. 

Today, I met up with my other friend and he was really grumpy. For context, I was complaining about him being really controlling and not listening to my input in things. Nothing really serious or mean about him. He's making a point about not being a controlling person and kind of just being a dick in general in all the ways I'd complained about. Like going out of his way to make sure I knew that I was wrong about all the things I said without making it obvious. But I mean, it's obvious that she told him what I'd said. 

I feel betrayed by my friend for going to that person and telling them all the things I said. But then I think maybe I'm the asshole here for saying it in the first place. I dont know if I should he annoyed at my friend for telling him, or annoyed at myself for saying it. I just thought it was normal to vent to people and have them just keep it a secret between them. So AITA? 

venting to my friend about another friend, only to have her tell him what I said
