You need to analyze your own actions - you are very focused on your ex. This question should be the least of your worries. Focus on yourself and your recovery - you can't go on like this because your emotional state will be controlled by his whim (even when he doesn't actively try - such as changing his Facebook settings).
I know it's not easy to do this and it gets easier with time. Take control of your emotions - distance yourself and don't worry about this :)3THIS IS NOT RELEVANT ANYMORE

Well when he blocked you he got peace lol. So maybe he unblocked in the hope you got the hint to stay away permanently. Stalking your ex is bad idea. Forget him, he's shown you mean nothing to him so why would you care what he does. Respect yourself and move on :) life's tooo short to even think backwards. he's an ex lol don't let him play with your head!!!0THIS IS NOT RELEVANT ANYMORE
