Why she took time let me try and answer
Practical aspects
#When you are in a long term relationship with someone or living in with someone you share access to common bank account , social media accounts when in same business u may share a manager a common household. U start sharing some responsibility and that person becomes your go to. Rash case he had access to her keys her social media accounts and they are represented by the same team
So cutting off a realtionship without cutting all across to shared areas can cause legal or social issues
Emotional aspects
When u fall in love with someone who has been there in a difficult period it becomes difficult to cut off ties with them at one go. No matter what u cherish what that person has done for you
For the sake of your and your partner dignity it is best you clear it out in private without Washing the dirty details in public to protect the sanctity of once cherished relationships
This is how the real world I know works ...j am not sure otherwise
I know since I was dating a child hood friend and we broke up due to him straying. But we told all that we parted due to reasons we do not want to discuss. I did not want the rest of the gang to judge him simple as that. To date we are civil when we meet rarely. Except my bro I don't think anyone knows what happened
