A relationship with a Narcissist has been compared to being on a roller coaster, with immense highs and immense lows. They have been described as the proverbial Jekyll and Hyde, one way one minute, another the next.
People usually get into relationships for love and the need to connect and bond with another. Narcissists get into relationships for entirely different reasons. They do not feel love and they lack the ability to connect and form normal attachment bonds with others.
Narcissists need people more than anyone. Because their entire sense of self-esteem and self-worth is dependent on the admiration of others, their emotions are a precarious balance of needing others and needing to be left alone.
