Ok so help and AIBU?

Hello.

Just wanted a bit of advice. A while ago a friend left her boyfriend (also a friend) and not so long ago she confided in me that she was talking to another guy who she was hoping to meet but she never did (she actually got back with her boyfriend). Nevertheless, me and my partner were talking today and I was telling him about this (I know I can trust him) as a similar Subject (a story for another day) came up and I used this as an example...anyway, her Auntie actually lives next door (balconies are side by side) and I think she may have heard even though we do always whisper. I dont think she knows about this story but I am worried she has overheard me now and friend is going to be upset..AIBU to think she may have heard and if so..is it best to advise friend just in case or leave it and see what happens.
I feel really bad about it all.

Why do you think her aunt might have overheard? She's pretty unlikely to have been out on the balcony in this weather.
