While those are all necessary pieces in a long term and stable relationship, so is basic human goodness. An asshole or a cheater is still the same person with or without the added benefit of social media. They have a choice to lie and cheat over being faithful and trustworthy. Freewill makes someone seek out a side piece of ass on Facebook or anywhere else. End of story. We are gluttons for gossip, instant news and what the hot girl we crushed on in high school ate for breakfast.
