Past being in love, really? (4)
I believe the answer is:
'past' is the definition.
(I've seen this before)
'in love really?' is the wordplay.
'in' says the answer is hidden in the clue.
'OVER' is hidden within 'love really'.
'being' acts as a link.
(Other definitions for over that I've seen before include "Finished like cricket session" , "jumped fence" , "A bowler's round in cricket" , "Action far more drastic than necessary" , "Passed" .)
