Facebook is a place for you to find back your lost contact friends, maybe find someone to share your daily life, chit chat with your friend, or to date someone...
but when you are in a relationship with someone facebook is a place for you to chit chat with your friend, play some facebook game...but not to FLIRT with someone or DATE with someone...
So i have decided to delete all my facebook accounts and my lover's facebook account too, this is to avoid that both of us will not flirt or date with someone.... ya i know you all will think of we do not trust each other, but the situation now is we really cannot fully trusting each other, maybe one day we really fully trusting each other, and our facebook will be reactivate...
