Hope - from what you have posted it sounds like your h is still in a kind of shock: I am not predicting that he will want to come running back, but equally I don't think he is any condition to do anything right now except get from day to day [a bit like us post bomb]. From what people post here it seems the more acute the crisis the longer it seems to take them to get back to comfortable reality.
I know that the 6 stages have come in for a lot of criticism. While the time lines and linearity might be questionable, the PROCESS seems to hold good. And as Snodderly and others have said again and again, it takes them a long time to get comfortable in their own skin.
I believe that your h loved you very much pre-MLC, and what he has done has shocked him, now he can see it mmore clearly. I didn't trust myself or anyone else. emotionally, for a long-time post bomb. I think many of them have to learn to live with themselves again, before they can share a life with anyone else. In fact my h said as much to me about a year ago in one of his few 'lucid' moments. I asked himm how he enviaged his future, adn he said 'I have to get a life before I can ask anyone to share it'.
