What legal actions can I take against financial control and violence?

For the past 21 years, my spouse and I have had a joint bank account, and I never had a personal account. After 20 years, I opened my own account, began transferring my pay into it, and received a few reimbursements meant for him. He accused me of "looting" his money and insisted that I should not use the joint account, only my personal one. He has always exercised financial control, with joint account OTPs sent to my phone and credit card OTPs to his. He now claims he can't manage the joint account due to OTP issues, though he's done it for 20 years and still uses it, insisting I handle all transactions. Now, I use my personal account to cover household and child expenses, while all money in the joint account is saved. I cannot save anything in my account, and he has forbidden me from using the joint account. He wanted to transfer the joint account money to his parents to develop shared property. When I objected, he became very angry and violent. What can I do?
