Deleting Facebook Messages from Friends Inbox?

[Dynamicwing672]

I want all traces of my conversation with my friend to disappear on HER inbox. I deleted the messgases we had on MY inbox, but im not sure if she still has them.
Is this possible? If i deleted the convo I had with her in my inbox, will it be deleted on hers?
if not, could i contact facebook and have them do this for me?
Thanks

Unless you have her password- its not possible.

No, she will still have the messages. Unless you ask her to delete them. Nd yet if she does, the old messages will reappear if you message her Or she messages you. So your stuck.
