Nice bloody vodka for one true love (7,6)
I believe the answer is:
kindred spirit
'true love' is the definition.
(a person's true love or soulmate)
'nice bloody vodka for one' is the wordplay.
'nice' becomes 'kind' (I've seen this in another clue).
'bloody' becomes 'red'.
'vodka for one' becomes 'spirit' (vodka is an alcoholic spirit).
'kind'+'red'+'spirit'='KINDRED SPIRIT'
(Other definitions for kindred spirit that I've seen before include "Person with common interests" , "Person with whom one shares common attitudes" , "One with interests matching another's" , "he's much like me" , "Close friend" .)
