Can someone help me with this facebook problem.?

Does the chat history still remain there after we un-friend someone. What happens when we add them as a friend again?

P.S. ten points for best answer.

P.P.S. sorry for my English.
I meant can the person I unfriended still see the messages I sent him.
I accidentally sent some rubbish to someone on fb and I don't want him to see it so I'm thinking of unfriending him and then again send a friend request which I'm sure he would accept

yes the chat history still remains,but that person is unable to see your wall..
If you add them again,he can see your wall again!

I'll answer you in a perfect and easy way but rate me full,

Eg 1; A and B are friends on facebook, they keep chatting for months and months on facebook.

Now A unfriended B,

Now 'B' Dosn't know 'A' unfriended him, B tries to find 'A' in his friends list,

B can't find 'A' but can see his name in his messages,

Now if B clicks on A s name he can see his profile as ADD friend.

Now if B clicks on add again then if A accepts his request then everytime when both are online they can see each other as online, or theyll not appear online to each other when both are online.

yes history will remain until you didn't clear the chat window (if you are asking about only your chat)

After removing the friend, you cannot see the friend chat history.

After adding again , if you see the message still , you can clear by going to message notification >> go to particular person >>click the drop down in the action >> delete conversation.
then messages will be cleared for ever.

Yes, the chat history still remains there in your account if you will un-friend someone.
