Narcissists can and will lie about everything they need to in order to get their needs and wants met. Some of the most common lies you will hear from them are as follows.
“I promise.” The narcissist will like to make a lot of empty promises. They will promise to take care of this, to do that, to be faithful to you, to show up on time. They will even promise you the impossible. They will make these promises in order to appease you in the moment but will rarely ever live up to these promises. If they do, it will solely be because they think it will help with keeping you under their control.
“It’s not my fault.” The narcissist will absolutely never accept fault or acknowledge their wrongdoings. If they do verbalize any form of accountability for their actions, it will solely be for the purpose of keeping you calm and content with them. Remember that even if they do this, they don’t actually mean it.
“Don’t worry.” The narcissist will nearly always tell you not to worry in response to your expressions of concern. They always want to be left to do what they want to do. If they sense that you might get in the way of their quest, they will convince you not to worry about it. You should definitely not believe them. Trust your gut. If you feel worried, you should probably be worried.
Another way they will deceive you is through gaslighting. In short, they will use lies in order to make you think that you are crazy. This is their way of breaking you down so you are more dependent upon them. If you are beginning to question your sanity, it is nearly always because you have been gaslit.
