From Anu Garg's A.Word.A.Day: maritorious, "Excessively fond of one's husband." The word is derived from the Latin maritus (married, husband).
Those who are excessively fond of their wives are uxorious. As A.Word.A.Day observes,
The word maritorious is rare, while uxorious is fairly well known. What does that say about the relative fondness of husbands and wives to each other?
