Is there an income level where you would be happy for your OH not to do a single thing round the house?
Say, they had the big job earning £200k would that be enough for you to be happy to take it all on or is it still reasonable to ask that they pull their weight at home?
If not, is there a figure (£300k/ £400k or whatever) or would you expect someone living in your household to contribute to its smooth running regardless of the £££ they bring in?
