'one who is unfaithful' is the definition.
I know nothing about this answer so I can't tell whether this works.

'crowd surrounds woman' is the wordplay.
'crowd' becomes 'lot' (I've seen this in other clues).
'surrounds' is an insertion indicator.
'woman' becomes 'Vera' (a woman's name).
'lot' going around 'vera' is 'LOVE RAT'.
