Why would a Narcissist tell you the only reason he keeps going back with you is because you keep coming back?

Because you are! Narcissists build a web of deceit, dishonesty, self loathe their victim, but yet can still love them in their own twisted minds. They are usually highly intelligent individuals, but use their intelligence in an egomaniacal manner and not for the better of those around them. They enjoy seeing their victims squirm, feel miserable and will make every effort to be sure their victims are NEVER happy. Hear what he is saying and kick this waste of skin into the garbage. You can do it!
