crd - Good on you for analyzing how you could have approached it differently. We all make mistakes, mistakes are learning opportunities.
Can you please add a signature to your posts? I can't remember if D is filed, or if you are just separating for now.
It is entirely reasonable to want to document the financial, property and custody approach prior to actually separating. Bring it up next time in mediation. Also think about what level of documentation you require, and how much you trust your W to hold to the agreement. Your W may have a different idea of what "documenting our approach" actually means.
