hey buddy. i had the same problem. theres no way out of this. what u can do is that merge your contacts with the facebook contacts using an app called contacts merger. however, if u donot have all the people's numbers that u have on facebook and dont want them to show up then u should disable the facebook account. go to availability and disable the facebook account. you will now only have your normal contacts. disabling is not like deleting the account. u can enable it back when u want to go online but then again contacts will show in normal contacts. what i do is that i disable facebook account when im not online.
