If you ever befriend or date a narcissist, run or prepare to be tortured.
It’s often unlikely that such a person would be able to hide their initial charm and chumminess for long, particularly as he or she begins to leech off your self worth to compensate for his or her lack of self-worth.
Simply put, narcs are parasites and there can be no mutual benefit from being with one. If you decide to stay in any kind of relationship with one, prepare to be tortured.
