I have similar dilemma. I’ve been pretty much dark with my H doe a few months now. It didn’t take me anywhere so far. He actually started the conversation about the D two weeks ago. He wants to file jointly and not use the layers. We met a few times during last 9 months of separation. I was especially upbeat and friendly during the last few times when we met. But, it seems to make no difference to him.
