ANSWER:
Providing a roof over you is the responsibility of your husband.
It is not your obligation that you use any of your money to provide for a home or it’s rent.
No one can tell you what to do with your possessions.
Whether you choose to help out or not, is entirely upon you. If he is unable to provide for you and you don’t have children, you have the right to file for divorce. You need to evaluate whether this is a good marriage to stay in or not on the long run.
