“After four years, most people have only half the emotional path to forget.”

Who Forgets Faster

People with avoidant attachment forget quicker than anxious ones.

“Avoidant individuals detach faster than those with anxious attachment.”

Gender Doesn't Matter

Men and women take similar time to move on from a breakup.

“Gender has no effect on how long it takes to forget an ex.”
