to be honest if you can afford it go for it as lottie says your giving somone a job i used to look after a lady and cook for her 3 times a week as her daughter lived a way and she would visit on the other days, never bothered me i washed her clothes and did general stuff,

couples who lead busy lives do need to spend more time with each other, these days relationships can be easily lost to lack of time good luck to you even if its just one day a week at least it takes some of the mundane stuff and makes way for more fun

think ya a posh git for getting a cleaner though
