Yes, you can love a man who loves himself too much. But should you?

Lucky girl! You scored a partner who is self-assured, confident, and focused. But at some point, you noticed that he’s more selfish than self-assured, and that confidence is actually cockiness. He’s certainly focused—but on himself. In fact, you’ve come to realize that the main thing you have in common is that you both love him.

Narcissism is more than just an irritating quality—it’s a bona fide personality disorder. “Everyone wants to be admired and loved,” says Stephanie Buehler, a psychologist and sex therapist who practices in Orange County, California. “But narcissists are grandiose, overly selfish, and exploitive. They have to be in the spotlight and don’t notice when their partners are in distress.”

So ask yourself: Is it worth maintaining a relationship with such a person? Experts say narcissists are unlikely to change, so the answer depends on how deep his self-love is. “Think of this as a continuum, from having a couple of selfish [1] attributes to being a full-blown narcissist,” says Stacy Kaiser, a Los Angeles–based marriage and family therapist. “The latter are the hardest to have a relationship with, because they are so ‘me’ focused.”

Your partner may preen and primp and adore compliments—but if he also shows empathy, concern about your welfare, and compassion, his positive traits may override his narcissistic tendencies. Just be sure to watch out for extreme behavior that could endanger your relationship—or you.

Scoring Key:
Count the number of true statements.

8 or fewer:
Keeper
He’s a regular guy whose ego lies within normal limits. Yes, he may sometimes be boastful, especially if you answered true to items 1 to 6. And true answers from 7 to 10 mean he might be vain—or simply an ambitious man on his way up the corporate ladder. “A person can display a few narcissistic traits, but not have a full-on personality disorder,” Buehler says. “Our culture breeds these qualities. Think of the audacity of some American Idol contestants!”

9 to 19:
Braggart
“This is a person who is moderately full of himself,” says W. Keith Campbell, PhD, associate psychology professor at the University of Georgia and author of the book When You Love a Man Who Loves Himself. The key is, he explains, to evaluate how your guy is narcissistic in the context of his overall character. For example, true answers to items 11 to 16 indicate a disturbing lack of empathy and compassion. But false answers to those statements indicate that his positive traits override his grandiose tendencies.

20 or more:
Egomaniac
Watch out! Your partner might be a full-blown narcissist—especially if you answered true to many questions from 17 to 25. These statements point to a sense of entitlement or aggression—the nastiest components of narcissism. “In that case, you have cause for real concern, and he could get worse,” says Campbell. “If it were me, I would run like hell, especially if you see signs of violence, infidelity, abuse, controlling behavior, or anger.”
