I haven't read your entire sitch, but when my husband and I were divorce I spent a lot of time listening to him talk about "trivial things." (i.e. his day, little things at work, the kids, etc....). I encouraged this and would ask more and more questions. My reason for this was I wanted my husband to realize what a great friend he had in me (something he always had, but forgot during the A). I figured that even if the divorce was going through, I wanted to act in such a way that my husband might someday look back and realize that he had thrown away the best friendship he ever had. My hope for doing this was that he would be able to look back with fondness and maybe even some regret about the marriage. I also figured that practicing good relationship skills would be useful in any future relationships. Even if the divorce had gone through, I wouldn't have regretted being a friend and great listener to my husband.
