Kdvor I could have written your post, with only minor differences. I think you should get the book and really commit to divorce busting, and follow the information from the homework you would got from your first post at newcomers (and I think Job will get you the MLC version of it soon).
My advice is to follow all the rules, especially since you see your H is already responding. Mine hasn't responded yet to anything I did, but then again he is a special kind of "stubborn". My mistake? I though I was DBing but I still initiated or asked for R talks! I think that has been detrimental and pushed him away.
Do your homework, give him space, work on yourself. As you say you are not happy with the marriage either, so work on what you can change, yourself.
Best of luck x
