The problem with you both dealing with your own finances is that most of yours are joint , not individual. You have joint kids, a joint house and joint bills. You eat joint food and go on joint holidays.
As far as I can see, your current system is that you have bills that each of you are responsible for . But that only works of these bills are fixed amounts and don’t change, and hardly anything is. And that they can be neatly divided into two.
But Utility bills, mortgages and insurance go up all the time. Even if you have a fixed monthly DD, then it’s reviewed regularly. Council tax is usually 10 payment as year not 11.
Childcare can vary month to month and the free hours change. Obviousy most other costs vary week to week, like food, clothe, travel , car costs, entertainment.
The other problem is how you classify bills as joint or individual. Eg Are the second car payments joint and the third car payments individual ? Are gifts for extended family joint costs?
For this to be fair, you would need to sit down every single month with your bank statements and add up every thing you both spend , classify it, add up and make a balancing payment from the one who had paid less to the one who had paid more.
Clearly that is ridiculous and too much work, so that why most couples have a joint account. The fact that your husband REFUSES to do this shows me three things
- he is paying less than his fair share of joint out goings currently and doesn’t want you to know
- he enjoys putting you down and acting like Mr Big whose feckless wife is bankrupting him and he want to hide any facts that would prove otherwise
- he has a higher income / other savings/ pension/ debt / expenditure that he doesn’t want you to know about.
So you need to think really REALLY hard about what this says about him and who he is as a person , the state of your marriage and if this is how you want to live. Because if he won’t change , your only option is to divorce.
This isn’t about money. It’s about honesty and openness, integrity, selflessness, putting your partner first and working for their good as well as your own , communication , shared goals and all that other good stuff that makes a marriage work.
At the moment you have the opposite. You are damaging your career and Pension ( by taking maternity leave and working part time ). Not for the sake of your children but for the sake of promoting your husbands person and career.
Meanwhile he is lying to you about money , probably ripping you off, putting you down. And grudging £12 for a day out with his kids when he earns nearly £100k.
