I too have followed your story for quite a long time. I'm not sure what there is left to discuss with him regarding "the situation." You have attempted to live together several times and it always ends up the same way. He is not going to change and unless you are willing to accept him as he is right now, then "the situation" won't change, either. Rehashing it won't do any good. Make your decision to either stay in the marriage or leave. At some point, you need to either be done or learn to live with it.
