So I'm making a plan and will be presenting that to him tomorrow when he's had sleep and time to think straight.
Your plan is for YOU. It is not necessary to show it to him. That will just give him the information he needs to keep stringing you along. You need to decide what you will and will not live with and then be ready to back that up. He has already lied, been emotionally abusive numerous times, and has started with the physical abuse. Your plan should be how to keep yourself safe, not give him an opportunity to negotiate.
