Because they're stupid and thinks they're cool (but I'm not generalizing some of them)

Perhaps it might be toxic relationship. A person who really cares wouldn't play with your feelings knowing that it might hurt you.

Some even make me think that they are building their resume of how much life they've ruined.

B/c their heart is full of pain

Lol it works both ways if u didn't get attached emotionally no one would have played with them .stop being naive and don't be attached emotionally so quick .ppl don't play with ur feelings unless u let them too!!!

Or maybe without their consent you are the one who is being played.... maybe they were not playing at all

They r a Plyer, obviously🤷‍♂
