OK, a married couple, 2 primary school aged DCs, each of the couple works full time hours.
Person A does all of the housework, childcare, food shopping, cooking, laundry, organises everything within the house, deals with the children when they are ill, plus everything else needed to keep the household running. Person B has long since disengaged themselves from doing any of this. Person A is very resentful at having to do everything, otherwise it does not get done. Person B will not discuss it or make any compromises.
Person B thinks that Person A is a total nag, and is out of order asking the to do anything regarding caring for their DCs or in the house. Person B has threatened several times to leave Person A when Person A has asked B to do something such as stack the dishwasher or bath one of the children, as it is apparently unfair to stop them from relaxing and to order them around and that they don't have to do anything in the house if they don't want to.
Who is in the wrong??
