Ok... it's a married couple. HE is not narcissitic by any means. Instead has a need to count for something as in being or becoming a hero, but he apparently hasn't made it yet, because he is still trying to "fix" his wife, who very well COULD be the narcissitic one, now that you mention it. She was brought up thinking that she was perfection personified and everyone owes her Everything. When she met the man, she set out to allienate him from his family. You know the case... insecurity to the point that she's jealous of everything that moves including her in-laws. Admits that she doesn't trust him out of her site or range of hearing. She uses naturally occuring as well as made up circumstances to manipulate the husband as well as the children. Uses the children for her own ends... through manipulation and lies. All the while, the husband realizes all her faults, what her father did to her, knows she peddled "it" over two towns before he met her trying to find acceptance and is now trying to "fix" her. She has managed to drive a wedge between her husband and all his family, including siblings. Did I mention that was her goal from the very beginning?

Need any more info? I'll be happy to supply it.
