Online dating and the narcissist
If the narcissist is unable to produce or claim an ability to do something better than you, then he/she will minimize or criticize your possession/achievement.
Nothing the narcissist has (and no one he/she knows, including family) is ever perfect enough to satisfy him/her.
The narcissist needs to be the center of attention, the most loved, most praised, most important person in your world (and his/hers).
The narcissist will try to cause fights and animosity between you and anyone else that he/she thinks you love more than the narcissist.
The narcissist will always suspect or accuse everyone within his/her sphere of influence of thinking or doing the same evil things he/she thinks and does.
He/she will constantly complain and criticize -- to the point of insult and verbal abuse.
The narcissist will complain about the same exact things for years on end, but will never DO anything constructively to improve (him/herself) or change the situation.
And no matter what the topic of any conversation may begin as, it will always wind up completely focused on the narcissist's self-pity, opinions, beliefs, misery, etc. The narcissist firmly believes he/she is more insightful and more enlightened than everyone else.
Despite the fact that the narcissist may be a blatantly vindictive, bitter, hateful, resentful, vengeful, bigoted person at home in his/her own domain, the narcissist will spend every waking moment painting a different 'image' of him/herself, and obsessively looking for validation by ensuring that everyone in his/her sphere of influence accepts and believes in the phony image.
