Ok it’s good that you have raised the subject . I’d consider this a starter for ten.
Sit down tonight alone and go through all your bank statements / credit card inc direct debits etc . Write a list of everything you spend on the house and bills. Every single penny.
Don't forget things like contents insurance you might pay once a year. Tv license, Sky, Wi-Fi.
Then divide that up and tell him he needs to pay his half on the day after he gets paid ( assuming that’s monthly) IN ADVANCE, just like you pay your rent.
Decide what you are doing for food and household costs.
“ We will each grab bits “ is a recipe for disaster, I’m warning you now. His bits will be a carry out and beers him and his mate on a night when you are out. Your bits will be all these tedious expensive things such as laundry power, TP , cleaning materials and dishwasher tablets.
You need a proper kitty to include ALL all of these. Ideally you should set up a new bank account for all costs and both pay into it each month. I’d get one with no overdraft or only a very small one. That way you will soon see if the £500 for bills and the £200 on food is enough.
What will happen about meals out / dates or if you order in food?
Then do the same for housework - write it all down and divide up. Make a wall chart / put it on an app, whatever works for you.
Remember that paying bill is a task in itself.
Make sure it’s not your job to remind him or monitor that he is actually doing His jobs or that you don’t have to “ ask him to help “.
There will never be an easier time to raise all of this than this week. Every week that goes by will make it Harder.
If you don’t sort this now you will end up hating him, I promise you.
