Wow, you poor thing, sounds like you need to house train DH
I work full time, and so does he - but we have a good balance - there are certain things that are his responsibility and things that are mine. eg - keeping the balconies neat and tidy is his, cooking is his and cleaning and washing are mone (though he often helps out with vacuuming).
Much harder to have that kind of balance if he is working 7 days though.
Have you considered getting a cleaner again? Just cos you arent working full time at a job doesnt mean you dont work full time with bubs?! Maybe swap positions with your partner for a couple of weeks, if you cna take over his duties in the business - i am sure he will realise then what it is that you do all day.
Dont give up on your work if that is what keeps you going and you enjoy it - you will end up resenting yourself and him in the long run!!!
