I would not solve my problem if i block her because our chat is still saved in her account. The main reason why i want to hide my profile to her is that I don't want that other people will see our chat in her account and then know who i am. We have some little sex conversation but i would like to have some privacy so this bother me. If someone would see our chat than can see my name and my profile picture even if i block her. I tried to change my profile picture to some nature and change my name to something that is not my name and right after that blocked her and after that change profile picture and my name back to real ones. I taught that she will then forever see my fake picture and name but the problem is that Facebook show again her my newest picture and name. She can always see my newest changes of name and profile pictures. I hope there is some solution for me. I don't want to delete this profile just because of her.
