You Feel Like You're Going Crazy
Psychopaths are the masters of manipulation. They have a way of turning everything around on you. You start to have little battles with yourself in your head, overreact, or start to second-guess yourself. Psychopaths like to confuse their partners and make it near impossible to have a logical argument. Even when you are in the right, you will never feel that you are because they will manipulate everything you say.
If you begin to question who you are and your values, you might be dating a psychopath. You start to think you are going crazy because you constantly doubt everything you do and say. You might start to become paranoid about things like what kind of clothes you wear, what you say to friends, or if people are talking about you. Who you once were and felt comfortable being might be a fleeting idea.
