I deactivated my facebook account..Will it be deleted if I don’t interact with the account for 14 days?

Not any it will never be deleted.You will need to delete the item manually.This option is within facebook assist.
But when you have just deactivated your own account it won’t be deleted forever

No them won’t it’ll never end up being deleted to create can reactivate the item by logging inside:-) Enjoy!

No.it will probably re-activate and return to normal when ever you log in next.
