Loved taking Ruby to a party (6)
I believe the answer is:
adored
'loved' is the definition.
(adoring is a kind of loving)
'ruby to a party' is the wordplay.
'ruby' becomes 'red' ('red' can be a synonym of 'ruby').
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'party' becomes 'do' (do is a kind of party).
'a'+'do'='ado'
'red' after 'ado' is 'ADORED'.
'taking' acts as a link.
(Other definitions for adored that I've seen before include "Worshipped, loved" , "Loved dearly" , "Really liked" , "Loved intensely" , "Loved enormously" .)
