'still finding you' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'can't arouse pity in' is the wordplay.
'can't' becomes 'unableto' (I can't explain this - if you can you should believe this answer much more).
'arouse pity in' becomes 'move' (synonyms).
'unableto'+'move'='UNABLE TO MOVE'
