A man who has not finished previous relationship is not a good material for a new relationship.
Relax! If he is your future, he will come back to you.
If not, you will find another man, one that is not a player.
Posting public comments on Facebook while telling to another woman that he has feelings for her ... give me a break.
The real question is: how many other women out there does he "have feelings" for?
The man is playing games, and is not ready for you.
But, you are ready for him.
That is imbalance. You have to play hard to get, to give him a chance to find out what or who he really wants.
