Friend photos and posts gone

My boyfriend is my friend on FB and we have been dating for 3 months but yesterday I happened to check my blackberry and looked at his page and it said zero friends and zero posts I thought weird.... I went home and checked his facebook and all of his wall posts, friends list, likes are all gone. I know he wouldn't hide anything from me because I already know his likes but his friend lists and past photos are gone just like that?? I've never seen anything like that before. I can see his profile picture and post on his wall and message him but everything else is gone. Any ideas?? Ever since FB changed things I get confused and yes the simple thing would be to ask my BF but I do not want to come off as being stalkerish or not able to trust him. Thanks!
