Have tried the conversation suggested to no avail - he just doesn't get it!
Id say youve got 2 problems here , obviously the fact that hes being financially abusive , and the other one that hes not listening to you and is minimizing it by claiming to not get it. Whats not to get ? His wife is unhappy and things need to change , simple really .
He's got this thing about transparency you see - that we're a partnership etc
But your not a partnership are you , you are not equal by a long shot. And thats not transparacy , thats controlling behaviour and checking up on you. He might say he doesnt mind if you check on him , but i bet he would . How would he feel if your parents / freinds knew he was doing this ? What if a freind called and you commented in front of him that youd have to ask for some money ? I bet hed be horrified.
Most kids get an allowance , freely given to them , most parents know that kids dont like to have to ask , your not even getting that.
You need to deal with this , dont assume its a man thing , it isnt , its controlling behaviour and its NOT about money. Its a reflection of how he sees you , inferior , less entitled , less than , and how he sees himself , as the boss , in control , more entitled ect ect. He doesnt see you as an equal , at all. He thinks his money is his and your not entitled to it.
You say hes ok in other ways but i wonder if youd be aware of it if he wasnt , you sound quite accepting of the situation. In my experience men who control finances ( therefore controlling movement , purchases , choices ect ) are usually controlling in other ways too.
Get your own bank account . Id be inclined to get an evening job that starts soon after he comes home.
