Having a great fondness for one's wife (8)
I believe the answer is:
uxorious
'having a great fondness for one's wife' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for uxorious that I've seen before include "Too devoted to wife" , "Very much attached to wife" , "Having great fondness for one's wife" , "Foolishly fond of ones wife" , "Fond of wife like our Sioux" .)
