I know I'm probably going to get yelled at for this, and rightfully so, I fucked up. But a few nights ago I [M28] hooked up with my good friend's ex [W29] and I feel awful. I've known both just a little over a decade, and have been friends with both of them the entire time. They were engaged for a few years before deciding to amicably call it off a few months ago.

I know my friend has been seeing other girls since the breakup, and I know that technically his ex is single again, but I realize what I did was shady and shitty. Just so we're clear, there is no interest in dating on either side and it was a one time purely physical screw-up. I'm not trying to justify anything, I just think people should know as far as advice goes.

Now here's the tricky part: do I bring it up with my friend? I know technically they are both single now, but at the same time I can't help but feel like I broke some unwritten "bro-code" (I hate that term) rule. I am really good friends with both of them, and see them both all the time. I realize I fucked up, but I'm not sure where to go from here, and IF there would be any benefit whatsoever from telling my friend (besides let go some of this crazy guilt I've been feeling).
