Some rewrite thought:

Hello W.

Hope you are xxxx. I wanted to check in with you on a few things.

First, I want you to know I appreciate your putting together a new schedule for S12. I understand the challenges for you both staying at your aunt's house and have no problem spending more time with S12, as you know I love being with him. Would it be possible for us to work together to achieve a schedule that works for us both? Nothing major, just wondering if we change it a bit.


Also can we finalize some of the recent outstanding financials? We do have some final bills from our old home. I was thinking it might be helpful if I get you those totals plus details of our storage payments. Plus, I am not sure how you are doing with the rental car...do you still need help? Let me know your thoughts on all the finances.


Finally, did you mention you have an idea for paying S12's tuition on your own? I am open to hearing your ideas and know we can work out the expense split together.

PS: Just a reminder, I also have your storage key!

I know this is rough and I do not know what worked in past exchanges or all the details: As Wonka said go back and see what worked, what WORDS work for her. But basically, make it more friendly.

What I do know is the drafts you have make it sound like you are trying to be friendly but are not friendly, you want your money and you want it now. And you are reprimanding her for 5 days vs 14.
