Former lover mentioned getting aroused (7)
I believe the answer is:
excited
'aroused' is the definition.
(I know that aroused can be written as excited)
'former lover mentioned getting' is the wordplay.
'former lover' becomes 'ex' (an ex-lover).
'mentioned' becomes 'cited' ('cite' can be a synonym of 'mention').
'getting' is a charade indicator (letters next to each other).
'ex'+'cited'='EXCITED'
(Other definitions for excited that I've seen before include "Thrilled; agitated" , "Aroused, enthused" , "In a stir" , "moved by emotion" , "Animated" .)
