Adulting Is He Zombieing you?
By now, you’d have heard of ghosting. Zombieing takes that to a whole new level: it's when someone who ghosted you reappears out of the blue.
The most common reason for zombieing would be that this person enjoys playing with your emotions – a huge red flag. While zombies are generally far from potential relationship material, you may consider giving him a second chance if he makes a greater effort to commit this time round.
