I need Facebook-stalker advice, and I'm the stalker. Should I give full disclosure or wait it out?

Okay, hear me out. I just met this guy and we have gone out a few times. He and I are not FB friends, but I did look him up and check out his profile. Well, apparently I sent a friend request to one of his friends which I didn't realize until this other person accepted it! I was tired and it was 100% an accident. As soon as I realized what happened, I deleted this "mutual friend" and now I'm freaking out. Should I tell the guy, or just keep my mouth shut?

Please, no comments on me being weird or creepy or stalker-ish. I would NEVER intentionally friend someone else. But of course I would look someone up, especially someone I'm going out with, and I have no problem admitting this. Everyone looks everyone up these days, and I expect him to have looked me up too.

As far as FB privacy goes, my understanding is that since my "new friends" are private, I'm only 50% protected. It depends on the other person's privacy settings whether or not his new friends pop up on his timeline/news feed.
(edit) - I guess I'm asking more about "relationship" advice rather than how FB works. Should I tell the guy I recently met that I accidentally friended one of his friends, or should I not say anything?

As soon as the other guy (say B, a he, for easy reference) accept your friend request, depends on B's setting whether keep his friends list to himself or not, if not, then automatically it will be shown to others. Now whether the first guy, the main figure in your story (say A) see it or not, that's another story that we don't know for sure. But as you unfriend B, your name will no longer in B's friends list; but still, during that said period you befriend with B, A might see it.
