No time to meet wife, prepared dating hints regardless (15)
I believe the answer is:
notwithstanding
'regardless' is the definition.
(I've seen this before)
'no time to meet wife prepared dating hints' is the wordplay.
'time' becomes 't' (abbreviation).
'to meet' is a charade indicator (letters next to each other).
'wife' becomes 'w' (abbreviation).
'prepared' indicates anagramming the letters.
'dating'+'hints'='datinghints'
'datinghints' anagrammed gives 'ithstanding'.
'no'+'t'+'w'+'ithstanding'='NOTWITHSTANDING'
(Other definitions for notwithstanding that I've seen before include "However" , "Despite" , "anyway" , "Regardless of" , "without being still" .)
