GG, I wonder if your H actually stopped taking the AD's, if he's been wanting to go off them. You mentioned it's strange that he seems to have gone bakwards after making great strides. I read that during the Acceptance stage of MLC, they can go backward because they are closing the doors to the different issues one by one.
The article also said that they have to do this all by themselves. If we interfere, we would end up delaying their progress through this final MLC stage.
