Well, if you feel you are carrying the entire burden of the household duties and the children it is time to put in place some boundaries with your W.
You could tell your W that while you understand there are issues between the two of you that may or may not be rectified you have decided as long as both of you are living in the house together it is time to re-establish household and childcare responsibilities. If she is not doing her share and you don't set a boundary it will continue.
