When trolling on Y!A takes its toll?

OK, so this girl asked if there was a rich guy in here. I thought she was trolling cause it (to me) was a stupid question. I was the only one who answered. She messaged me through Y!A and asked if I was really rich. I said, Yes. Then she said if I had facebook. I said, Yes. We added each other and started chatting. For couple days now. Coincidentally we live in the same town and city. She wants to meet up in a public place. Now for the twist.. I thought she was lying and I was the one ending up being the troll. Should I just come clean or save myself from embarrassment and ignore/delete her forever? I'm actually not rich at all. I don't own a Porsche , a mansion or own an albino tiger as a pet. :/
