Opti, today is not tomorrow. Don't let the unknown drive you. Deal with the papers if and when they show up.
I was so stressed out about when the papers were gonna show, every day checking to see if sheriff was outside my door to deliver them. I had built it up in my mind to be more than what it was. When they finally arrived, I panicked and got all upset until I talked to my A who told me I had nothing to worry about because papers were done incorrectly, that as far as the courts were concerned, nothing had been filed. That wad middle of march of this year. No correct papers have been filed since. If she was so adamant to get D, she would have quickly corrected the error. She hasn't, her delay has allowed me to gain strength and now I can accept whatever she decides to do. Now, I'm detached totally and I am free of her drama.
Slow everything down, stop talking to her, she does not have you or the girls best interest at heart. This is about her. Detaching, IMHO, is the #1 thing you can do for yourself, your family and your marriage. As long as you are detached, you can think clearly and maintain control of you. If I could do this over, I would have taken the advice given to detach sooner.
The more you detach, the more she will spin out of control as part of her plan is to take you on the journey with her.
