AITA for spilling a secret? #shorts

Hey! I’m a 23F in grad school who lives with some awesome people. Everyone here is in the same program. One of my roommates told me that she used to date one of the other students (let’s call him Troy) but it didn’t work out. It’s an open secret among the second years but us first years don’t know anything about it. Except me. Troy has also been going around telling the first years not to date in our program. So last night I got drunk and was talking to another first year and she revealed she had a crush on Troy and was trying to get rid of it. I told her that Troy used to date my roommate and that made her feel better. She promised not to tell but now I’m freaking out because I’ve never spilled a secret before. And I don’t want to break her trust. AITA? #aitah #aita #shorts
