I think two sessions a week is a bit much. Unless a person is in real crisis, having more than one a week (or every other week to help process the therapy) would generally be counterproductive. Even my book (which I believe has really good info) is often too painful for survivors to read in the course of a month.
Maybe negotiating the "requests" or "demands" is something you can do before getting unhitched. Divorce should be the last option imho.
