tl;dr NO SHIT, it is not healthy to keep taps on ex's

Previous research has found that continuing offline contact with an ex-romantic partner following a breakup

may disrupt emotional recovery. The present study examined whether continuing online contact with an expartner through remaining Facebook friends and/or engaging in surveillance of the ex-partner’s Facebook page

inhibited postbreakup adjustment and growth above and beyond offline contact. Analysis of the data provided

by 464 participants revealed that Facebook surveillance was associated with greater current distress over the

breakup, more negative feelings, sexual desire, and longing for the ex-partner, and lower personal growth.

Participants who remained Facebook friends with the ex-partner, relative to those who did not remain Facebook

friends, reported less negative feelings, sexual desire, and longing for the former partner, but lower personal

growth. All of these results emerged after controlling for offline contact, personality traits, and characteristics of

the former relationship and breakup that tend to predict postbreakup adjustment. Overall, these findings

suggest that exposure to an ex-partner through Facebook may obstruct the process of healing and moving on

from a past relationship

Facebook is so unhealthy in so many ways.

I wonder if it needs to be regulated.
