Narcissists always want to be the centre of attention.
S/he will expect their partner to acknowledge their achievements, talents, and appearance at all times.
Approximately six per cent of the population has Narcissistic Personality Disorder (NPD).
NPD affects more men than women -- 7.7 per cent men and 4.8 per cent women, according to research published in The Journal of Clinical Psychiatry.
So how do you know that you or your partner has NPD?
Dr Forrest Talley, a California-based clinical psychologist and Dr Gene Beresin, executive director at The Clay Centre for Young Healthy Minds at Massachusetts General Hospital have identified warning signs that you may be dating someone with NPD.
Here are some red flags to look out for, as reported in The Independent:
They might make you feel bad about yourself
Don't expect a narcissistic boyfriend or girlfriend to be genuinely happy for you.
Instead, they will most likely be overly critical or attempt to downplay your accomplishments.
They only like to talk about themselves all the time
If you're dating someone extremely self-absorbed, your date night conversation will most likely revolve around his or her achievements, success and interests.
Constant praise is what makes them happy
Narcissists always want to be the centre of attention and will expect their partner to acknowledge their achievements, talents, and appearance at all times.
They are demeaning towards other people
Egocentrics often obsess over the negative aspects of other people's lives.
Even their close friends and family members may not be spared from the judgment.
Narcissists often think they can do a better job than others, which reinforces the belief that they are always right.
They are sensitive and also overreact
When a narcissist's emotional needs aren't met, their reaction is often grandiose.
Many narcissistic people may appear extremely angry or cry until the other person apologises.
They lack empathy
Your partner may offer to come over when you are having a bad day, but their motivation is most likely self-serving.
