Why does she still, have to be a fraking a$$hole about it?
Have you asked her? I mean what's the worst... she becomes more PITA? But seriously... for a while there my W was being really, really over the top towards me. I finally had enough and told her that a) I understand she is done, b) that this cold, bitchy attitude isn't necessary to make me understand she is done, and c) if I am doing something that entitles me to her attitude please tell me so I can do something about it.
Her over the top attitude really pulled back after that. Because I wasn't doing things that justified it, and she admitted it. She's still cold some days, particularly when we've had a couple warm days. But it did help.
In your case you're actually divorced... I don't see why you can't politely and civilly say, "I don't appreciate it when you say XYZ, or treat me XYZ." She may not even be conscious about it.
