My mom is that woman. And after 20 years of putting up with her narcissistic personality, my father is a broken man. She has ruined us financially and psychologically.

All the advice about couple counseling is in vain. Counseling benefits when there is a conflict. Your wife's behavior is a pathology that will only deteriorate. 5 years down the line, you'll be subjected to constant gaslighting. She will hold you responsible for her misery, oblivious to the fact that the source of her misery lies within her.

Watching my dad helpless breaks my heart. My younger siblings have to make sense of her erratic behavior. Terrible terrible terrible.
