Sorry to hear about your sitch. You found a good place for support. I would like to suggest that you focus your energy on making the changes even though H is not receptive at the moment. Things are constantly changing, so it is key for you to keep making positive changes to your beliefs, thoughts, words and actions. Over time, all the small changes you make add up and H will notice.
I would also like to suggest that what works is almost always counter intuitive. In other words, pursing your spouse right now will push him farther away. He is in the fog. Puppy Dog Tails is very wise and you should read as many of his posts as you can.
