Input: So this involves three people. A friend of mine who I've known for about eight years, Jess. We're not really close but we went school together, had overlapping friend groups and lately we were both chaperones in the same camps.

Then there's Cindy. She's a close friend of mine who studies with me.

And lastly there's Brad. He's Jess' boyfriend, they're together for 5 years.

Brad and Jess had some rough patches a few months ago and got separated for a few weeks. During this time Brad met Cindy. They started going out and Cindy was head over heels for him. They were seeing each other for about three months when I met Jess in a group setting. She casually mentioned that she and Brad were back together. The thing is I knew that next Saturday Cindy had planned a date with Brad. So I told Cindy. She was so heartbroken but she's my friend and I couldn't have watched her dating that lying idiot (he told her he had broken up with Jess for good). Now the thing is, I haven't told Jess that Brad and Cindy were dating while she and Brad were already back together. I'm pretty sure she doesn't know about it. I feel like as an outside person it isn't any of my business. Jess is a friend but not that close and I don't want to be caught in the middle of something. But a friend of mine said that I'm an asshole for telling Cindy about Brad's capers but not Jess. AITA?

not telling a friend that her boyfriend was dating someone else
