Going out with partner once having personal charm (4)
I believe the answer is:
exit
'going out' is the definition.
(thesaurus)
'partner once having personal charm' is the wordplay.
'partner once' becomes 'ex' (an ex-partner).
'having' says to put letters next to each other.
'personal charm' becomes 'it' (intangible human quality: 'she has it'. I am not sure about the 'personal' bit.).
'ex'+'it'='EXIT'
'with' is the link.
Can you help me to learn more?
(Other definitions for exit that I've seen before include "walk away" , "Means of egress" , "Leave the stage" , "Depart" , "farewell!" .)
