That's the thing is that people with personality disorders (narcissism being one of them) are extremely charismatic. My ex is the same way. He would lie about going to his ex's house, talking to her and lie about other stuff and he was never wrong either. But every time I tried to leave he would smooth talk his way back into my life. It took a few months of wanting to go before I finally just was finished with it. And even a year later he would text me! Randomly. And I would ALMOST fall for it. I could still feel myself wanting his attention but I just told myself that I knew what he was really like and I ignored him. People like that, you seriously have to remind yourself of all the things he has done to you. Because he WILL do it again. Good luck
