Like husband with memory going into retreat (6)
I believe the answer is:
ashram
'retreat' is the definition.
(type of religious retreat)
'like husband with memory' is the wordplay.
'like' becomes 'as'.
'husband' becomes 'h'.
'with' is a charade indicator (letters next to each other).
'memory' becomes 'ram' (RAM is an example).
'as'+'h'+'ram'='ASHRAM'
'going into' is the link.
(Other definitions for ashram that I've seen before include "Hindu religious retreat" , "Guru's community" , "Place for religious retreat (in India)" , "Hindu hermitage" , "etreat" .)
