I don't understand how this shows the dark side of social networks. It does show the ugly underbelly of human interaction, but that side is no uglier for the technology used. The guy was lonely, his gf was worried about something else, so he became insecure & impetuous and decided to move on, as young people are wont to do. Only today it's happening through websites and webcams instead of phone, telegraph, snail mail, or message-in-bottle.
