Second: As others have said, separate all emotion from this portion of the show. You have now entered the phase where you are dissolving a business partnership gone awry. Get. A. Lawyer. Refer everything stbx says to your lawyer. Do not engage. Ask the lawyer what you're entitled to. Ask to have stbx pay legal fees. Go for absolutely everything you are entitled to and settle for what makes sense to you, knowing that post D your stbx could and may not honor any agreements. You've been married over 10 years. You are entitled legally. It's not his decision, it's the law's.
In terms of the emotions, let them out in a safe place when he's not around. Be gentle with yourself.
