Facebook Graph API / FQL : Is it possible to know which one of two users has unfriended the other one? -

-

using facebook fgraph api or fql, can know if usera has unfriended userb if have usera permissions?

in fact, here's i'd achieve:

there 2 users whom have all permissions. friends (i can see using api).

one day, see not friends anymore , i'd know which 1 of 2 has unfriended other one. possible, in way or another?

i'm pretty sure best can detect they're no longer friends because they're not listed in each other's friends list.

however, facebook makes point of banning application lets people know when unfriends them.
