I (29M) am unsure if I should tell a woman (27F) I dated that her friends are sharing her secrets

I (29M) went on 5 dates with a girl (Clare 27F), we later broke things off as I found out she was dating around and leading me on in a way. I felt bad at the time, but we talked it out and ended things cleanly and it has been a few weeks since. I was a bit hurt how things ended but I did not convey that to her and just let her be.

I have recently met her friend James, he seemed to know a lot of intimate details about our relationship which I found odd. So I talked to him a bit more and asked how he knew… Turns out Clare was telling some personal things to her friend Ryan in confidence.

And Ryan has been telling a bunch of guys in his friend group including James. To be honest it feels wrong that she told Ryan things in confidence and asked for his advice and Ryan has been spreading those details to other guys. And those other guys have been gossiping behind her back.

I don’t have any intention of getting back together with her, but I felt bad about people gossiping behind her back, especially on intimate details (such as me asking her for sex on the 4th date, and her turning me down).

I know I might run into Clare again this week at a party. I am not sure if I should bother telling her what is happening behind her back?

I am not close to Ryan, James or Clare socially so I don’t have much to lose. I would have to tell Clare that Ryan is leaking her secrets and tell her not not to confront Ryan or James about it as they would figure out that I told her.
