Love and the Trumpster
One thing you must realize when you love a narcissist is that your experience is one-sided, as he is incapable of either giving or receiving love. This concept may be hard to grasp at first, but if you have ever been in a relationship with a narcissist than this theory definitely explains a lot.
If love is not being exchanged in the relationship, then what is? Anyone who’s ever researched the topic of narcissism has most likely heard of the term “narcissistic supply.” Narcissistic supply is the form of exchange that a narcissist will accept from those he is in a relationship with to gratify his insatiable needs; but this supply is not love, because narcissists are rarely capable of receiving love.
Since people need love to be emotionally healthy, the narcissist is doomed. Because he cannot accept love, he can never actually be connected in a close, intimate relationship with anyone. In the end, this leaves him lonely and empty; he cannot truly thrive in his close relationships, and ultimately this deters him from a quality life
