Although Facebook can help loving couples feel connected 24/7, there’s a downside to all that connectedness when the relationship sours, a new study contends. Using Facebook to track an ex may seriously impede the brokenhearted’s ability to heal and move on, said study author Tara Marshall, of the psychology department at Brunel University’s School of Social Sciences in Uxbridge, England. “People who engaged in Facebook surveillance of their ex-partner, [meaning] people who more frequently looked at their ex-partner’s Facebook page and friends list, reported delayed emotional recovery after a breakup compared to people who engaged in less surveillance,” Marshall said.
