Not read all of the posts, but from what I have read, Stressedoutwife - you need a slap!!
Your dh is working hard to provide a safety net for your dc yet you want to eat into this safety net and spend money on what - fluffy cushions and posh face cream???
It is not about how much your dh earns, it is about what he is trying to put away in case your dc fall on hard times.
Wake up to yourself woman, do some charity work, gain some self respect and look around you. Most people would kill for what you are moaning about.
You say you had shared access to the finances but overspent it. So now you have an allowance. Fair enough, if you can't control the money you should not be in charge of finances.
Your husband is working hard, to provide you with a nice house, a leisurely lifestyle, security for your children, and still you want more??
I feel sorry for your dh, you sound like a financial liability.
