So my friends and I have two different group chats. One with more people, including my best friend's boyfriend, and one with just me, my best friend and two other people I'm close to. I wanted to share something a bit more personal so I told them to check the more private group. My best friend's boyfriend then logged onto her account to spy and see what was being said in the group he wasn't apart of. I feel like it's a huge invasion of my privacy. I went to the more private group specifically because I didn't want to share something personal with people I wasn't close with. He knew this and purposely logged onto her account. It's not like he came across it on accident. He didn't even hide the fact that it was him. When I said hello to (who I thought was) her, he straight up said that it was him. I then brought it up to my best friend, saying it made me uncomfortable and that I think it's wrong. She told me to talk to her boyfriend about it, said it wasn't her problem and left the group. So now she's pissed at me. Am I the asshole?
