Thank you for your question!
The name that you used appears to be of a female from Indian background, however; your residence appears to be in Australia. (Through your IP Address) I will reply based on that information.
I would suggest to speak with your husband about it. How do you feel, etc. Tell him what you would like to happen. Even though I understand the concept of “extended family” for it is very Spanish as well, I do not understand how “in-laws” could continue to think that their sons or daughters are still little children under their jurisdiction.
What you are describing is an issue when you have some dependency on others. As long as there is any sort of dependency from your part, things will be this way. I hope your husband has a “say so” in this; otherwise, if he is just a “mama’s boy,” then you didn’t get married with an adult but with a “child.”
If you could earn a living that will give you some freedom, as long as you are willing to speak up and defend that this is important for you.
This is as much as I could say about the situation you described.
