Some couples are instant and true friends after their breakup -- rumour has it they exist. If those ex-couples want to be Facebook friends, so be it. But the rest of us should defriend, at least for awhile.

I want to see if he says anything bad about me.

I want to see if that coworker/friend/person I always had suspicions about really is just a friend or not.

I want to remember all the reasons we broke up.

Why should I defriend him? He should defriend me!

I want to make sure we're not headed to the same places.

I need to gather information about him.
