No, I have never had an emotional affair on Facebook, or anywhere esle for that matter. In fact, I refuse to even have a Facebook account.
For one, Facebook is responsible for 25% of all divorces these days. In my opinion, it's just not healthy for anyone, especially married couples, to interact with so many people - many of whom are of the opposite gender. In my mind, it's like playing with fire.
I just don't think God intended for people to be so "social" and so willing to divulge so much intimate and personal information to others.
It's also a great place for predators to roam about, looking for someone to devour. Let us also not forget that many people on Facebook are deceptive and deceitful (just like on any other social network).
I know this is off-topic a bit, but another thing to worry about, regarding Facebook, is that it is a CIA database collection program. Facebook's front is that of a social network, but what it really is, is a database collection program that entices people to give away personal information, contacts, photographs, names, dates, phone numbers, friends, associates, and travel plans...to name a few.
It has been said that "Facebookers" have willingly forfeited enough information on themselves, family, and friends, that it has saved the CIA tens of millions of dollars and millions of man-hours, if they were to go about collecting this information through more conventional means.
And, please don't think for one second that Hubpages and every other social network has not left the door open for the FBI and CIA and every other super-sluething agency to watch and monitor your comings and your goings.
Be careful out there folks - there are a lot of bad apples in circulation and a lot of wolves in sheep's clothing. It would be wise in this day and age to be more guarded.
