I think if your H is not wanting to talk about your separation or progressing towards D , but at the same time is not indicating any thoughts of a reconciliation then he is at the very same stage as my W.
The very easy answer to this is they dont know what to do. They are going backwards and forwards trying to find a path but just cant figure it out.
This is where you need to be very patient. If you are like me at all then your path is not so clear either . It may take a long time for a WAS to recommit if they ever do. My point is that at some stage the LBS needs to test that what they are saying is actualy the truth. If the LBS can gain some trust in the WAS by doing this then the path to reconciliation could well be smoother.
Oh and I am no expert , I tend to learn by making mistakes , all of them
