I'm not sure I follow--it looks like nothing has changed, so suddenly you're wanting him back? When NOTHING has changed? Even in the unreal eyes of Facebook?
My personal suggestion is to stay OFF Facebook, go back to complete no-contact. If you find yourself obsessing about him, distract yourself. Get therapy. Go to Al-Anon. Take a class. Get a new haircut. Make some new friends. Run a marathon. Whatever works.
I still have occasional dreams about my exes. Sometimes they are nice dreams, sometimes not so nice. But they are DREAMS, and mean very little except that something apparently popped up in my unconscious that made me think of them.
