Log in email address to Facebook!?

[Marmalade]

If you remove an email address you use to log into your FB account and replace it with a new one, you can still log in using the deleted email address for a while, even though you are redirected primarily to a notification page that states the account has been changed recently.. Could anyone tell me how long FB takes to dissociate your account from that email address you removed?
Oh and I do NOT want the removed email address to be linked to my FB account anymore! Thanks everyone for taking your time!

If your request is aren't proved ,please log in with your previous email . To confirm your email changes ,it may take a month to prove that change but if you antagonize the two emails with your facebook account, you may end up loosing it
