7. They lack honesty
Another way to spot if the person you’re dating is a narcissist or not is to pay attention to their actions and measure them against their words. As many experts say, these people lack trustworthiness and follow-through. This can range from always canceling appointments to constantly failing to keep their promises and agreements.
You might also notice that they don’t support you 100%. One minute they might be there for you when you need them, but they’re gone the next. If you observe that your partner is always inconsistent between what they say and what they actually do, you might be dating someone who is a narcissist.
