"I will be finalizing the rest of the bank and money stuff by the end of next week. I will be looking into a new cell phone, as you did not email me the password. It doesn’t make sense to keep all of this jointly if there is no other “us” left. I will separate other bills and such as I can, and will keep you informed. I would expect you to make the debt transfer by the end of September, as well. If you think it is more fair, just transfer over half, and I will figure out the rest on my own."
As for the money stuff, quit trying to collaborate. He doesn't need to know any of this. He does not need to be kept informed. He doesn't get to decide what is "fair," the court did that. I am sure he knows you expect him to transfer money. If the money is not transferred by Oct. 1, then contact him at that point:
"H, the amount we agreed to in monthly support has not been transferred. Please advise."
