Is AUTHOR wrong in the post ? POST : Okay, so title says it all but now for the story. I’ve known this friend (We’ll call him Jake) for about 13 years now and I consider him practically my brother however I’m worrying that I’m doing the wrong thing right now. Basically him, I and my girlfriend at the time would all go to fires during the summertime which is where his future gf (we’ll call her Jess) comes into play. About a week or two into the summer my girlfriend dumps me and I take it pretty bad, like I stop going to the fires and basically just shutting myself out until Jake comes over and forces me to go to the next fire. We go and arrive early so we are the second group there and sit down. The next person to show up is Jess and her friends so she sits down right next to me, throughout the whole night we’re flirting and just really hitting it off, one thing leads to another and I offer her a ride home and we make out a bit. Through the week we talk and blah, blah, blah which leads to us hooking up, I’m her first which is important later. After however we stop talking as much and about 2 weeks later I get back together with my ex. Later in the week We go to the next fire and discover that Jake and Jess are now dating also which is only surprising to me because Jess and I are the only ones who know about hooking up. Anyway, a few months go by which leads us to tonight, she came into my work and was very flirty to the point co-workers noticed. 


  So, TLDR ; AITA for not telling my best friend about hooking up with his now current gf who believes he’s her first
