Comedy of Errors: Advice Needed

I have found myself in a bit of a pickle and need some advice from my blog readers.

About a year ago I joined an online forum. I was an active member and posted often, but after a few months the drama and stupidity of some of the members got to me and I deleted my account. Recently during a case of bad insomnia I rejoined under another name, but purposely choose not to include details about myself, as I wanted to remain more anonymous this time and hopefully avoid the Internet trolls. I didn't disclose my location and listed my profession as photographer instead of law.

I've been posting quite a bit lately back and forth with another member on a variety of topics. Last night one of his posts included a reference to his location, and since it was NYC I decided to click on his profile and see if he was hot (LOL...just being honest!). His profile photo was a picture of something in his house and it looked oddly familiar and I knew I had seen it before. I realized that the person I have been corresponding through the forum with is MR. FUN. I searched the member photo gallery to see if he had posted any photos of himself and he had, it's definitely him.

So here's where I need advice. Do I tell him it's me? There's no way that he knows it's me, I've been very careful not to disclose much about myself or my location and my screen name is completely unique from any of my email addresses or instant messenger names. I don't want to mislead him in any way, but I've definitely said things in that forum that I had hoped wouldn't be read by people I knew and I'm hesitant to "out" myself. I feel bad that it's been going on so long, but I can't be expected to search the photo gallery for every single person that responds to one of my online postings to see if I know them or not. Out of the millions of people in the world, what were the odds that the one who was chatting with me was someone I knew?! What would you guys do??
