Not sure on your financial status but wife has no paid employment I gather so whose money pays for takeaway food? and why when she has all day does she need to buy ready made foods, specially when she is planning all these trips.
How much mess can 2 people make, you are out all day at work. Maybe you can employ her to keep your house clean. Weird.especially when her mother helps. CL I fail to see how you are in control, but its your life.
Just let her eat all the left over food, its a health risk anyway. I guarentee when this is sorted she will come up with another complaint. Is your job flexible or demanding,in terms of free time who has the most. By all means do your own cleaning up after yourself, but I wonder what she actually contributes to this friends/marriage partnership. I still get the feeling she has power over you and you are afraid of something so deep rooted that you do not allow it to surface. Anyway as you can see improvements and feel in control and this issue has been validated and sorted, I wish you well.
