You shouldn't read anything into the FB status. I understand you, had the same thought. My W hasn't changed her status even thought she took her ring off on the second day after BD in the beginning of May and has told everyone she knows (that are important to her). It could be that he is not ready to tell "the world", that he will change it when D is final (in the future), that he forgot or simply do not care what FB says about his relationship status. You cannot mind read his actions based on history because he is not the same person.
Also, neither of you is "entitled" to anything. You are not entitled to him or of his feelings of love. He is not entitled to have you waiting for him or to be able to date and still be married. We all understand your feelings or doubts, we have or had them as well.
All you really can do now is concentrating on yourself, for YOU. The only person in the world you can control. Give H space and time. Work on your issues that you told us about long-term, take care of yourself short-term and try to do things that give you joy. Try to find activities that prevent you from thinking too much. Especially with other ppl. Neither of us on this site wants to compete with others about our S. But he will only choose the very best Marie you can be, regardless of other ppl involved or not. By then you maybe don't want to be together any longer. Or maybe he won't, but by then you might feel so good that it doesn't matter. Who knows?
What happen will happen, you cannot control H. And I am sure that you would only want to spend the rest of your life together knowing that he wants to be with you and made a choice by himself.
Good luck going forward! I hope you have a support system around you.
