Aroused former partner mentioned (7)
I believe the answer is:
excited
'aroused' is the definition.
(I know that aroused can be written as excited)
'former partner mentioned' is the wordplay.
'former partner' becomes 'ex' (an ex-partner).
'mentioned' becomes 'cited' ('cite' can be a synonym of 'mention').
'ex'+'cited'='EXCITED'
(Other definitions for excited that I've seen before include "moved by emotion" , "in a state of agitation" , "Thrilled; agitated" , "In a stir" , "Hot" .)
