She quit being a wife in August, has not cooked, cleaned the house, laundry or dishes.
This part concerns me. You said you both work, different schedules. Why is cooking, cleaning, laundry, and dishes "being a wife"? Perhaps these expectations are part of what has contributed to where you are now. Have you expected her to do these things because she is the wife? Household chores should be the responsibility of the household. You doing dishes shouldn't be helping out, or picking up the slack, but rather part of the duties of living in a home with other people.
