No matter how much you reason with them or explain your stance on a certain topic, they’re not going to see your side of things.
“When you’re dating a narcissist, they probably won’t compromise on an important issue,” Kouffman Sherman says.
If you’re dating a narcissist, it might be hard to get them to care about what you’re going through, whether that’s the death of a loved one or just a hard day at work.
“If you’re crying or are upset, they get bored very easily and can’t really understand what you’re going through, mostly because it’s not that interesting to them,” Kouffman Sherman says.
Thoughts or feelings that aren't directly related to a narcissist's own won't hold their attention.
There are many ways this can show up in your relationship, but even something as simple as them showing up late all the time and never apologizing or thinking about how their lateness affects you is a red flag. Narcissists believe themselves to be "special" and unique, and by extension believe they can only be appreciated by other "special" people.
If they're dating you, don't be surprised by comments such as, "Wow, no one else has ever understood me like you do" or "You are so different from everyone I've ever met" — even if you've started dating.
And as soon as you fail to comply with all of their expectations, they may look for someone else to fill the gap.“In a normal relationship, you’ll have low selfishness, the ability to forgive, and you’ll be supportive, generous, and empathetic,” Kane says.
