I don't think it would make him any more appealing but it might account for the mala dance.

I hate the term co-dependent being used about a relationship with a narcissist.  

It's illogical.  Since when is a narcissist co-dependent?  no a narcissist is making use of the co-dependent's ability to give and take.  The problem arises for the co-dependent because it never gets to the take part, the narcissist is a user and they've got the other person giving til they drop.  and they never give back.  They do not work well together long term.  They work well together for as long as the normal person can muster the strength and courage of heart to pay for the both of them.
