I don't think it's unusual, depending on your circumstances. I don't know what DH earns. I could only give you a vague estimate.
When we were starting out we both had a tight grasp on our finances as we were saving for a wedding, house etc on low incomes.
Time has gone on and DHs pay has sky-rocketed, mine is still low-ish as I am part-time. We no longer need to budget, don't need to have specific savings amounts, no bills come out of my account, we have a joint credit card that pays for shopping, petrol etc. We're both quite frugal and largely on the same wavelength regarding spending.
The forecast looks quite bleak in relation to DHs job post-Brexit so his income this year is likely to be dramatically less. Hundreds of thousands of pounds less than previous years. We've been discussing getting a joint account and moving some money around in preparation for this as we'll need to be much more careful with money.
It's not so much knowing down to the last penny what is coming in and going out, for us it's about being on the same page regarding acceptable spending, being able to plan together, and communicate openly about money, and of course being able to completely trust the other person.
I come from a very poor background and the last 5 or so years of not worrying about money has been amazing. I never take it for granted.
