What can I do to forget what I thought I could have with my Narcissist ex boyfriend?

He love bombed me and made me believe he was everything I wanted and that our future would be like I always dreamed. But it was all an illusion and he didn’t even love me. How can I see him for who he really is and forget him? He is a narcissist.
