My best girlfriend finally broke it off with the married guy she'd been seeing for the past year. Of course she didn't know he was married when she started seeing him, despite suspicious signs.

That doesn't bode well for any of us.

While warnings seem redundant, and books like Greg Behrendt and Liz Tuccillo's He's Just Not That Into You and Jamie Callan's Hooking Up or Holding Out spell out exactly what not to look for, it bears repeating: If a guy looks sweet, but acts sneaky, you should probably be wary. Has to run to catch a train after work? A tan line on his ring finger? Wants to meet for lunch, and go to hotels? Duh!

Even if it's just that little voice in the back of your head that keeps whispering, "This doesn't feel right," then it's probably not right.

The Internet is a constant source of distraction and deception. I've heard of more guys who either get hooked on cyberspace porn, or start to roam in places they shouldn't be. (Why do you think David Duchovny is being treated for sex addiction?)

It seems there's a web site now for almost everything. One of my "happily married" guy pals just met someone from a site that specializes in married couples seeking discreet affairs. A quick Google search, and philanderers.com is just a mouse click away.

My friend insists he's only looking for fun, not out to destroy his marriage, but I know differently. We FWW women can smell divorce coming a million miles away.

Because, divorce stinks; it smells like sex, lies, and the Internet.
