Some of what you are experiencing with your H sounds similar to my sitch. My H makes a lot of promises to do things and then he never does them. If I have the nerve to bring it up later, then he gets very upset with me and complains about all the roadblocks in his life.
Like you, I find my H's indirect and abstract "communication" style very hard to understand. He clearly is miserable but takes little to no action towards reconciling or even making himself happy.
I am still on a bit of a rollercoaster emotionally, where somedays I am very detached and sometimes I backslide.
Keep up the good work.
