TIFU by outing my sister to my friend

r/

I’m aware I’m the asshole, i seriously don’t know why i even told my friend.

I had gotten permission from my sister to tell my best friend and my partner but I didn’t ask for this friend, I just told her.

I brought up the fact that my friend knows today when talking to my sister and then it hit me that I fucked up.

She didn’t get mad at me or anything but as someone who is also queer I feel incredibly terrible that I even did such a thing.

I apologized to her saying it wasn’t my place and I should’ve known better. She responded saying she was just surprised and then followed up with some jokes. I told her I would take her out as an apology.

I still feel incredibly terrible, what can I do to make sure this doesn’t affect our relationship long term?

TLDR: I told my friend my sister was queer and I didn’t consider the fact that she wasn’t out yet.
