Me and he share pretty much equally
We both now work part time - he earns more but I also have a pension so not too far apart
He does the outside - cars, gardens, hens, fish, house maintenance , I do washing, ironing, cooking and about 60% of house work - he does the stairs and will help with beds, ceilings, skirtings, windows etc. He also knows how to put a wash on , hang clothes and work the dishwasher
He pays council tax, electric and oil. I pay groceries, and things like BB, subscriptions and phones
We share holiday costs, we take turn about if eating or drinking out, we "treat" each other to concerts and theatre visits
We have a joint account which his money is paid into which I sometimes tap into - if we are hosting for example, I have my own account where my wages are paid into which he has no access too. . We have joint savings that we pay in what we can , when we can
All in Id say we have a 50/50 split
