The double edged sword of loving a narcissist is that the very qualities that attracted you to them are what they resent the most, because they know deep down they cannot ever mirror your greatness.
And because you are the one closest to them, you become “onto them,” and begin to question their behavior. A narcissist’s greatest fear is being exposed that they are no longer truly special, which is why they must have abundant supply from abundant sources. Which leaves you, their partner, abandoned, discarded, abused, and traumatized.
If you find these behavior patterns ring true for your relationship, break free as soon as possible. They will never change, merely because they think they don’t have to.
