"I told him to have a nice day and I hung up the phone.ever since that phone call I feel sick to my stomach.
DIVORCE = SPACE
You should give him as much as possible. If you don't want a divorce then make him do the work. If it is what you want then that is a different story. But I think (and I am mindreading) that you feel sick becasue you do not want a divorce. Is that correct?
So if you do not want it then you need to start to think counterinutitively. Stop pursuing him and let him file for the divorce and do all the work. Go dark or no contact with him while he is pursuing the divorce.
Believe none of what he says and 1/2 of what he does. Have NO EXPECTATIONS.
