Old man admitting the woman bolted (6)
I believe the answer is:
dashed
'bolted' is the definition.
'old man admitting the woman' is the wordplay.
'old man' becomes 'dad' (both can mean one's father).
'admitting' is an insertion indicator (admit can mean to welcome in or accept).
'the woman' becomes 'she' ('she' refers to a woman).
'dad' going around 'she' is 'DASHED'.
(Other definitions for dashed that I've seen before include "Thrown down as hopes sometimes are" , "Rushed headlong" , "completely destroyed" , "hurled at" , "completely spoiled" .)
