It's been two years since they broke up. When I ran into him the other day, it was like the break-up had just happened. That dude is an emotional flatliner!

Emotional Flatliner 

Someone who shows no emotional response to anything, no matter how poignant or stirring. They’re either so repressed that nothing gets through their emotional firewall, or so disconnected from their feelings that even a child’s laugh, a heartfelt poem, a soulful song, or a breathtaking view leaves them completely unmoved. Picture a human equivalent of a flatline on an emotional EKG—zero reaction, just a blank stare.

"I played her my favorite song, the one that makes everyone cry, and she just shrugged—total Emotional Flatliner."
