My heart is breaking for you. This is a tough spot to be in but in healthy relationships you are free to be you and healthy relationships don't make demands on you.
Yes boundaries need to be set but when you have been raised in this unhealthy way it takes time and help to establish acceptable normalcy. A great counselor can help you navigate through this new to you territory.
Moving is a great idea. Cutting ties may also be a great idea for a time but learning how to master setting and sticking to your healthy boundaries is the best. Controlling people don't like being told what to do or how to do it but you have every right to be respected and live your own life. You are 30 and it is your life.
Read up on books abour co-dependency and setting boundaries. Learn to use the recommended suggestions. It will take repetition on your part because we learn by trial and error but it's okay to make mistakes and learn from your mistakes.
Your live and quality of life will improve as you learn how to set healthy boundaries with not just your parents but all of the people you must interact with in your life.
This won't be easy but it will be very worth it in the end. They may even cut you off instead of the other way around which is fine because they are adults too and you will try to respect their wishes just like you want them to respect yours. Success on your journey to healthy and wholeness with your family.
