Edit: Literally all of her exes*

She doesn't do anything with them. In fact, it probably has more to do with them than it does her. I don't have any of my exes on any of my social media. No desire to. What would be the point? Is this validation seeking, knowing that her exes are still most likely interested? To see that she's doing better off than them? What is the psychology behind this, because I do not understand it personally.
