Thanks tulips and dalila. Yes, I will take the emails to my T.

I think I'm just going to accept that this person and I cannot work together. He is very well respected and has worked on many cases successfully, but for whatever reason, it is not working with him and me, and causing me too much stress over our inability to communicate and work together. I need to focus on other things with the divorce, not interpersonal relations with the team members. I will try to move forward and find someone else to fill his role. Yes, there are going to be some angry people, such as my H. I will lean on my L for help with all of this. (And my T too.)
