Obviously, I don't know the ins and outs of your financial circumstances... but based on what you've said already, I really think that this incident is a sign you need to look into them.
Who pays for what. and when. What do you both think is fair.
A pp said that it looks like if you had a windfall it would be spent on the family, if he did, it would be spent on him... there's something wrong with the attitudes.
Obviously things should be proportionate but it does sound that he has proportionately more disposable income than you do and its spent on him, not on the family. I could be wrong.. but its a question of correctly identifying his attitude.
You've been told off by some for not having joint account. Given his attitude I still think you should keep your finances separate. after bills etc.
He's treating you like the mum of the family, you are supporting DD and him, so of course you have to pay for any of the boring things like coffees and car repairs etc. If he still owes you for the last set he should give you the compensation money for that.
How much is he saving? He needs to save for your DD's future too, not just rely on you. You do the bulk of the childcare too.. what does he do to even that out?
What does he spend his disposable income on ( no need to answer any of this on here but its a good idea to have a real think about this yourself) are you able to spend the same amount on your pursuits
Who pays for the bulk of DD's expenses
Who contributes so paying off credit card debt.
You said that it has more or less become the expectation that you pay for holidays/outings... is that because if it was left to him, they wouldn't happen. Maybe you should suggest that you pay 2/3 and he pays 1/3 towards these things in future, just like the bills. He also pays 1/3 towards credit card repayments in case he doesn't regard these as household bills.
Make a spreadsheet so the real picture is demonstrated.
Its not just about money, its about how equal the partnership is, and about how equal the effort each puts in. Do you do all the planning, organising Christmas, buying presents for his family. Christmas cards for his family. I'd stop all of that and let him take over the reins on things like that. He is a grown up too.
Another cautionary note. All the money that you use to subsidise him now... is money that could be going into your DD's future (unless he's also making a contribution to that but it's a "boring" detail maybe) And more importantly going into your pension fund. This may seem like a long long way away... but you need security for you and DD and as you get older and time flies by. And by that time you have far less wiggle room. It will be too late.
See a financial advisor and work out when you will have repaid your mortgage and if you are saving enough for your old age. He won't be subsidising you at that point. Do you both have life insurance?
To me it seems daft that you earn 2/3 of household income, but you are probably not able to save or see the benefits of working so hard because you are oversubsidising someone who feels very entitled and has just demonstrated exactly that to you now. He thinks you owe him because he's got used to your generosity. At the moment subsidising him is acting like an extra mortgage on your income. Not a problem as long as the proportion is fair, but it is a problem if his contribution in terms of finance and effort and thought is lacking
