There are many signs of a true narcissist. The three most prominent ones are a lack of empathy, a sense of entitlement, and interpersonally exploitative behavior. If you have been shown time and time again that someone is incapable of putting themselves in your shoes, that they feel like deserve to be treated like royalty while everyone else deserves to be treated like dirt, and that they will do whatever it takes to get what they want, regardless of who gets hurt in the process, chances are, you are dealing with a narcissist. Also, a narcissist will often employ what is known as splitting, or taking responsibility for everything that is good or positive while blaming everything that is bad or negative on you. Other signs are an attitude of superiority, need for control, lack of responsibility, lack of boundaries, and an exaggerated need for attention.
