There is no doubting that social networking sites can lead to the breaking up of relationships. But there is another side to the tale, which is that people are moving onto other, perhaps better, relationships at the same time. Social networks can put you (back) in touch with those you have lots in common with, and that common ground is often the starting point for long-lasting relationships.
As painful as break-ups can be, they can sometimes be the right thing for all concerned. What’s to say that the new relationship, founded on the steps of Facebook, isn’t THE one that will last? Even if it doesn’t turn into a spectacular coupling, it could be the friendship that is needed at the time. Which has to be a positive.
Social networking sites can help foster friendships and perhaps more besides.
