Was chatting to MIL today, we don't have a brilliant relationship but I wouldn't call it awful in any way.
Anyway the subject came up about me returning to work after a year off on Maternity leave (took a year due to health reasons)and progressed to her finding out I don't make my DH, her PFB, a packed lunch every night ( he works in a factory with a horrible canteen so takes a sandwich etc).
She catabum mouthed me and told me it was terrible that im at home all day doing nothing while he works FT he at least deserves his lunch made 
I cook his dinner every night, wash and iron his clothes, do all the housework and shopping myself, run to the post office on his errands(he has a business too), look after 10 month old, mow our lawn etc. is it really that awful not to make him his lunch FFS??
I think I'm not but MIL and subsequently my mum think I'm BU and should be standing every night sorting out his lunchbag for the next day.
BTW before baby came everything in our house was split 50/50 and I am going back to work part time in a few weeks.
So AIBU?
