As Salamu alaykum sister,
I’m sorry to hear of the difficulties you are having with your husband. Yes, you are right. While I am not an Islamic scholar, your husband is the one who should be providing for you and your money that you earn is yours. If you chose to share it with him or pay bills, contribute to the household that is a blessing for you, however it is not his entitlement.

I suggest dear sister that you remind him of the Islamically prescribed duties of a husband and wife concerning money issues. If he still persists, I would kindly suggest that you both discuss this issue with your imam, as often times men need reminders from other men, especially imam’s regarding Islamic issues. While this is not intended to humiliate him, it is intended to act as a reminder to him of what rights Allah has given to you as a wife.

Your in our prayers sister please let us know how you are doing.
