Breaking up is hard to do. And maintaining contact with an ex can make the distress of breaking up even worse. Of course, cutting off contact with them is more difficult than ever in our social media obsessed day and age, but a new study shows that some people are more likely than others to Facebook stalk their former partners after a breakup, the Huffington Post reports.

The University of Hawaii at Manoa and Ohio State University looked at men and women between the ages of 18 and 42 for their survey, all of whom had experienced a breakup within the last year. They found that partners who were most anxious and invested in their previous relationship were more prone to Facebook stalking post-split. In other words, those who were more hurt by a breakup were more likely to prolong their suffering by stalking their ex. Social media sites are like “virtual scrapbooks for relationships,” the study said, which explains why suffering exes are so keen to turn to them in times of need.

The takeaway from the study? Block your ex on Facebook and other social media sites. Thought it might seem hard, it’s for your own good because in the end, the only way to lessen the pain of a breakup is to forget about it.
