Is AUTHOR wrong in the post ? POST : Context: This happened in high school. I'm currently in college now. We (me and my bff) made up a week after this incident occurred, but I felt like I never gotten the validation (or invalidation) from my actions so what better way than asking Reddit? Also, the best friend in question has another issue that would be great for another post on this subreddit, but I'll console the internet again if it's eating me like today's scenario is.


I've been best friends with this guy ever since I got transferred to the same grade school as him. We've been inseparable all throughout our school lives and I was very happy that we went to the same middle and high school together. We never really had a major issue of conflict until around sophomore year of HS. 


He comes to me seeking comfort or advice when something goes wrong in his life. I don't really stick my nose where it doesn't belong, but he's my best friend so I'm going to stick by his side no matter what. I never hesitated to be there for him when he tells me things no one else knows, even his own family or his boyfriend at the time! This is how he came out to be as not only gay but transgender as well. The latter will come into play later on. Of course, I supported him wholeheartedly. I didn't really get it at the time, and everything made sense later on my journey of identity. Anyways, moving on!


During our time in high school, we became acquainted with this pair of twins, but the conflict of the story involves only one of them since I had more classes with her than my bff did so I think we got along a little better than she did with him. 


One day she gave me a piece of cryptid piece of paper and told me to look at it when I got home and come back to her once I decoded it. I didn't get why she couldn't just tell me straight up what's wrong, not to mention we sit next to each other in the next class, but whatever. Took me some time to crack most of it and tl;dr my friend doesn't believe that my bff is really transgender and that he's doing it for attention. Of course, I was shocked and appalled by this bold accusation and confronted her about it. 


She told me to not tell him what she said. I immediately told him when we met for lunch. I couldn't bear hiding this knowledge from him and normally I would've asked my mom for this kind of advice at the time, but it became too much to wait it out. Not to mention it could've been worse if I told him earlier. All he did was reply with, "I know." and stormed off without a word. When I got home I got a call from that friend who asked me why did I do that. I can't remember how I replied exactly, but I do know that I was in a complete state of despair and just a crying mess over the situation.


So Reddit, am I the asshole for being an honest friend? Or am I the asshole for not keeping an incriminating secret from my best friend? My bff and I haven't really talked to each other ever since we graduated. In case if you're wondering, the other friend transferred somewhere else before junior year started since she had a medical issue since birth that she was getting surgery for around that time, so I assumed she wanted to focus on her recovery. I know her family runs a store nearby that I can walk to any time, but I never really had a proper reason to go inside. I highly doubt both of them will see this, let alone use reddit, so that's why I'm not using a throwaway. 


tl;dr my best friend since grade school came out to me as transgender in high school. A mutual friend told me that he might be doing it for the attention and I should not tell him she said that. I told him as soon as I saw him since I couldn't bear the guilt and he didn't talk to me for a week. AITA?
