It is a near-universal impulse after a breakup: the relationship ends, you reach for your phone and, almost automatically, you look at your ex’s social media. Who are they with? How are they doing? Have they moved on?
For many, it feels harmless or even useful — a way to stay informed, find closure, or steady yourself after an emotional shock. But a decade of psychological research paints a different picture: repeatedly checking an ex’s online profiles rarely helps healing and often prolongs pain.
“Looking up your ex online — you’re strengthening the brain connections that when should be trying to weaken them,” says Joanne Davila, a clinical psychologist at Stony Brook University.
Studies in cyberpsychology and human behavior consistently link “ex-partner surveillance” on social platforms with poorer emotional recovery after breakups: higher distress, stronger longing and less personal growth. “These findings are indicators that individuals haven’t let go,” says Michelle Drouin, a psychology professor at Purdue University. “That impedes recovery and increases the emotional trauma, or the connection to the past partner.”
Emotional pain drives people to seek information, and breakups create an information vacuum. The internet makes it easy to fill that vacuum: “We’re able to look up anything we want: ‘How’s the past partner doing? Have they moved on?'” Drouin notes. Yet obtaining those answers tends to make it harder to move on.
Neuroscience helps explain why. After a breakup the brain’s attachment system is activated — the same system that responds when we feel insecure. Davila describes checking an ex’s profile as an attachment behavior: a reach for something familiar when you feel alone. It may bring momentary relief, but it doesn’t resolve the underlying hurt.
Social media also hijacks reward systems. A new photo, location tag or cryptic caption triggers a small dopamine hit — a brief sense of control or knowing — which reinforces the behavior. “They check and they feel better,” Davila says. “And then, when they feel the same way again, they want to check again.” That cycle resembles patterns seen in anxiety and obsessive-compulsive disorders and can prevent people from working through emotions. Under stress, ambiguous posts are often interpreted in ways that deepen longing rather than promote healing.
Practical steps to support healthier recovery include ending the surveillance and allowing emotional ties to weaken. Try setting temporary digital boundaries: Drouin recommends a social-media break of about 30 days as a detox. Replace checking with active redirection — exercise, walks, calling friends — activities that help regulate distress. Reframe the breakup as information: if the relationship ended, it likely wasn’t right for you, and the split can be an opening to healthier future relationships.
