I just read this whole thread and wanted to throw in there that it might not be a good idea for a realtor to sell their own house in a D situation... especially if she's as spiteful as it sounds. It would seem reasonable in a time of conflict that the two of you hire a neutral person.
I'm very sorry for your situation.
