Either way, woman's not denying love affair (5)
I believe the answer is:
Here is my best explanation:
'affair' is the definition.
'either way woman's not denying love' is the wordplay.
'either way woman' becomes 'eve' (palindromic woman's name).
'denying' is a deletion indicator.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'not' with 'o' taken away is 'nt'.
