Why Aren’t You Unfriending Your Ex On Facebook?

After splitting with their boyfriends and girlfriends, 59 percent of people don’t delete their now-exes from their Facebook friend list, while 74 percent continue to Google their former lovers. Granted, the research comes from dating site YourTango.com, which is focused on the hetero market, but part of me (based on zero scientific evidence) thinks the rate of exes staying Facebook friends would be higher among the gays, since our friends are the same sex as our dating pool, and more often than with heteros, removing an ex on Facebook would remove a key link in our friendship circles. Thoughts?
