While I voted for hitting the road jack, I should it modify it: maybe you can maintain the r/s in separate households. He should have his own household and his only cleaning service or maid. And if the cleaning service or maid is unable to keep the place in the condition that you would find satisfactory because they are not working 24/7, so be it. It would be his place and not your responsibility or area of concern.

Even if he starts thanking you, it would never be enough. You would become more and more annoyed and exasperated. It is a dead end!
