After a breakup – messy or otherwise – there are a few "what not to dos" when it comes to social media. One difficult temptation you may face after a breakup is checking out your ex on social media sites like Facebook. It seems innocent enough to want to know what he's up to, right? Wrong. In fact, a recent British study found that people who kept up with their exes by regularly viewing their Facebook pages experienced "greater current distress over the breakup, more negative feelings, sexual desire, and longing for the ex-partner, and lower personal growth." In other words, if you're spending a lot of time on Facebook seeing what your ex has been up to, then you're more likely to be unhappy and unable to move on from the breakup.
