Being narcisstic can also mean not giving your significant other equal time... It seems like a bad joke, but there are really people out there who tell you about themselves for hours, and when you try to tell them about yourself, they mostly want to hear how wonderful your life is now that they're in it. It's having that "Let me tell you about me, and then you can tell me about me" kind of attitude.

Having healthy self-esteem is wonderful, but if the only thing you're focusing on is your appearance, it's also a bit shallow and short-sighted.
