Yeah, I agree. I think you should sit on it for right. You have it saved, so you can always post it later.
I think right now, you want to give off the impression that you are thriving. And if word got back to H that you are struggling, that wouldn't be attractive to him.
Remember, if you want H back, you have to ATTRACT him back. Be confident, cool, sexy etc. Fake it for now if you have to.
You have to make him think "oh sh!t, Sparks is moving on and happy. Did I make the right decision?"
