Looks good. With the kids you might want to hold off using the legal terms like "custody arrangement" and instead refer to "coparenting time".
Stay strong. You can and will do this. This is the first day of the rest of your life. You will be happy. Hopefully your H will have an epiphany and realize he can't and doesnt want to live without you.
You have done everything right. You did everything you could. Walk away with your head held high. You DESERVE to be treated with LOVE and RESPECT. Expect nothing less.
You have a lot to be Thankful For. HAPPY THANKSGIVING EVERYONE!!! PMA
