Where is his salary paid in? Joint or personal? Is this his personal spending?
Is there enough money in the joint account to pay for all essentials, save for annual and irregular expenses like insurance, car replacement/repairs, emergency fund, Christmas, holidays etc?
How much personal money do you have to spend? What personal savings do you both have? What would happen if there was a big necessary expenditure like a car or new roof/windows - can you pay for this?
It sounds like a lot of money, but whether it is unfair and/or too much depends on your overall finances. If you're mortgage free, child free, savings and pensions are sorted and you also have access to the same amount of money, it could be OK.
However, if you have no savings, no personal spending money because he spends it all on him, or you're struggling to cover essentials because he's effectively spending the bills and food money on his own personal indulgences then obviously not.
