As long as ED has been filed it will not be affected by absolute divorce being granted. You not signing the divorce papers will only draw out the time frame, but it will not stop the process altogether and it will not change the ED. ED is all assets and debts from the date of separation. It is in your best interest to wait for the final appraisal of the accountant regarding the ED settlement but it will have little affect on the actual divorce.
I would say that the judge will make a ruling on alimony amount (which would cover, house payment, car payment, medical insurance, etc) at the time that ED is complete. He can not carry you on his insurance after the divorce but he can pay you for medical insurance coverage that you retain on your own.
The court order stands unless the judge rescends it or a new order is put into place. It’s unlikely though that the entire amount will be awarded permanently so you should be prepaired to make some adjustments. There are some other posts I’ve read that are very negative about this. Do you have an attorney?
