How did I get stuck in an exploitative and manipulative relationship? 

How did I get here? How is it that I am living with this on a daily basis, even excusing it, downplaying it, and justifying it? How did I come to accept this behavior as normal?

Narcissistic mirroring is defined as a manipulation tactic used by narcissistic individuals to create a false sense of connection with another person by mimicking their thoughts, feelings, interests, or behaviors. It is a calculated and intentional act to activate the other person's feelings of empathy and cause them to feel connected to the narcissist. It is a manipulation to lure their target in and to earn their trust, for their own self-interest and gain.
