An intervention might work in some cases...but in my case who would intervene?
My SO wouldnt take anything I said to heart, nor is she take any advice or criticism from her Mother or her mothers side of the family, her sisters she only gets along with ~35% of the time as they think more like their mother, and her father is as happy as a pig in slop as far as our situation is concerned...so he wouldnt do anything that might take away from his maid service and errand runner, or the exponential time he now gets with our daughter.
