I'm posting for some advice or suggestions on how to best manage our finances.
Married, 2 kids each from previous relationships, none together.
His eldest is 18 and an apprentice on £18k. My eldest is 19 and also an apprentice on a similar wage. The other 2 are teenagers in school. We live with mine and he sees his occasionally. Nothing fixed now they're older and are out with friends all the time. Open visiting at our house, which they both do when they want to (live local).
We earn roughly the same. I get CM from my ex and he pays CM to his ex (similar amounts).
Currently sharing everything. Income and bills/outgoings all treated as joint. We have a bills account and joint current account. We always seem to be overdrawn each month even though we earn decent amounts (£90k joint) and have a low mortgage (£500) and no childcare etc
I'm get annoyed with him still sending money to his eldest in the region of £170 a month as she always spends her wages and begs for more for takeaways, clothes, nights out, petrol etc. She doesn't pay board to her mum. I don't give my eldest a penny. He pays £200 a month board towards bills and groceries and buys all his own things after that and runs a car. DH also likes buying more gadgets and clothes than me and doesn't seem to have a good awareness of budgeting.
So, I'm looking for a new way of splitting things. What would others do in these circumstances?
