Should I go in for an extra-marital affair?

[???]

So, instead of shutting down your 16 yr old niece when this started to happen, you let it ride like some kind of perv? Dude, are you creepy or what? lol She is young and just playing a game.

Listen, if this girl is interested in anything, it's one-upping your wife. She's jealous and wants to prove your wife is nothing to be threatened of ... and no one envies a woman who's husband is cheating on her -- especially not with her NIECE who is practically a baby. No one respects a man who would do that either, so if you want to spend the rest of your life watching this chic smirk at your family - your wife and kids - keep doing what you're doing.

There's still time to get out of this with a portion of your reputation intact. Start saying things like, "Ten years makes such a difference. Girls weren't this flirtatious when I was 18." and "Lucky boys today don't have to wait for anything." If she steps it up a notch in response, laugh and say, "I didn't say it was a good thing." Act like you've been completely turned off, and start talking about how virtuous and honest your wife is, how it makes her even more beautiful, etc etc. Get it so you only brag up your wife or criticize her niece when you talk and she'll eventually leave you alone -- and hopefully not act like such a tramp in the future.
