Financial abuse?

So I'm not sure if this is the right place to post this or not so let me know and I can change it but..

I'm a 21 year old stay at home mom of a 1 year old. My husband and I have been together 6 years. He was never abuse, we've had our differences and problems of course but he's always been a really good guy.. he makes decent money and pays all of our bills. However I feel that he may be abusing his power in our house.. he has always prided himself on taking care of us and me not having to work. He brags about it often. However I am not allowed to have any extras and he can have whatever he wants.. he spends at least 300 a month to build his project car while I am denied extra money for things we need in the house (garbage bags, napkins, cleaning supplies). I am expected to keep within his strike budget. For everything we need in the house. My mother passed away a little over a year ago and I was given a very large amount of money from her life insurance. I spent it on things for us however he kept track of every penny. The money quickly ran out after we purchased a new house for our growing family, a new car, and other random furnishings (again all only for our family and he kept track) I'm afraid to ask for money for anything for myself and I have no way of getting money myself. I posted some items online recently to sell and he quickly shut it down by telling me he suddenly had plans with what I was selling.. I'm not sure if maybe this is just normal and I'm being over dramatic or what I just need advice.
