When in a relationship with a narcissist, you quickly learn the predictability of his or her reactions to certain circumstances. That is why you walk on eggshells, so that you don’t accidentally trip one of those hair triggers and set off an explosion. (Even though you are NOT at fault.) You tiptoe around as to not make them upset somehow because you know the awful reaction that would happen if you do, but every once in a while the narcissist will withhold that terrible predictable reaction and you are shocked and feel instant relief. You even feel gratefulness to your abuser that you had been spared his or her fury.
Subsequently, you then see a faint glimmer of hope that the narcissist has potential to change his or her nasty ways and slowly transform into a human. However, that is part of their great deception. Narcissists are incapable of change, incapable of having empathy, incapable of truly loving another person. So, narcissists throw you a bone once in a while to confuse you and keep you off track to think that all of their previous overreactions were just misunderstandings or “in your head.” These fake-outs keep you dangling by a thread.
Those very limited instances where the narcissist doesn’t rage at you when you were certain that he or she would because they commonly did in the past, confuse you greatly and help you maintain hope for the relationship. But this hope is futile. See the narcissist for what he or she really is, a soulless monster. No amount of abuse, whether be it emotional, physical, spiritual, financial, sexual, etc. is worth putting up with because a good person who truly loves you would never attempt to abuse you in any way.
