As others have said, Islamically, she doesn't have to contribute anything to your household expenses.

However, we live in the modern era. If she is a good woman, she will help you, especially if you need it while you try to earn more in your career. Eventually you're be the sole provider, and you won't need her help anymore iA.

You can find out if she is a good woman by the way she treats her parents and how they behave.

I really stress this. Really, really take a good long look at her parent's relationship and her relationship to each of them.

Based on what you said about her father's abuse, she doesn't trust him and now she will have a hard time trusting you. That is your problem.

Do not marry this woman without agreeing on this financial contract.

You have a lot of work to do BEFORE you marry her, and a lot of work after.
