OP, I could have written your post.
We are exactly the same: work full time, cleaner for 4 hours every two weeks actually. Costs 50 quid per two weeks, so 100 a month (quite a big house, 3 bathrooms).
We do not have a lot of money as only been in house 2 years but find that a cleaner is one thing that we really benefit from. I hate cleaning and so does DH. At weekend I just want to chill with DS and DH, not clean the toilets.
We saw BIL and his wife at the weekend and told them that we had got a cleaner.
Exactly the same reaction from family as you 'comments from in laws mainly about this, vary from me being lazy, to wasting money, to we've obviously got to much money, to not being a good wife/mother. Thing that most gets me is it is always aimed at me, not Dh, as if cleaning/housework etc entirely my responsibility!'
YES!!!
WHY?!! Why is it me? Why my responsibility? I work full time. DH does too?!
And then bloody sanctimonious SIL saying 'Oh, I like cleaning'. Yeah, sure you do. Give me a fucking break.
And ' Oh, that's expensive, think what you could do with the money? We don't have spare cash like that'. No, but you have a new Golf on HP for 300 quid per month don't you, SIL
With the money we could probably have two/three takeaways a month. Or go out at night twice a month to the cinema/dinner. Or, oh, no sorry, we don't have a babysitter, so we can't.
Hence the cleaner!
