Dr. Jekyll and Mr. Hyde
It seems like your partner is two completely different people; they can change in a split second for no reason. They will act one way with you but a different way when around your family and friends, and maybe a completely different way when around a boss, or strangers. Psychopaths are experts at blending into whatever crowd they're around, like a chameleon. They can make anyone like them.
When you first began dating, they were charming, sincere, everything seemed perfect, and they would say everything you'd want to hear. This is because they wanted you to believe in them when in reality they were really just setting their traps. Now that they know you are dedicated to them, they are able to reveal more of their true selves without fear that you will run away. They can show their evil ways and feel they know how to manipulate you.
