Each guided round by husband? Showed sign of relief, perhaps (7)
I believe the answer is:
exhaled
'showed sign of relief perhaps' is the definition.
'each guided round by husband?' is the wordplay.
'each' becomes 'ea'.
'guided' becomes 'led' ('lead' can be a synonym of 'guide').
'round' is an insertion indicator.
'by' becomes 'x' (multiplication sign**).
'husband?' becomes 'h'.
'ea'+'led'='ealed'
'x'+'h'='xh'
'ealed' going around 'xh' is 'EXHALED'.
(Other definitions for exhaled that I've seen before include "Breathed out" , "Sent out" , "Gave off" , "blown out" .)
