Was I wrong to not tell my friend her ex is dating her mate?

I've known my friend Jodie for around 2 years. I remained friends with her and her ex-boyfriend Harley after they broke up about 3 months ago. They obviously don't get along with eachother, but despite that I was on good terms with both of them.

Recently, Jodie's close friend Leah got together with Harley. I knew about it and decided it was best to not get involved in the situation, and not tell Jodie. Leah was also close friends with Harley back when he and Jodie dated. Im friends with Leah too, to make things more complicated.

Anyway, fastforward a few weeks, Jodie finds out about them two. She gets quiet upset and cuts contact with me, Harley and Leah. I found that she deleted me on Snapchat. Here is where I messaged Jodie to try and explain things:












So yeah. Was I wrong to not tell her about it? Let me know what you guys think. Honest opinions are appreciated. Thanks!
