1. First make up your mind about status of marriage. You can try to stay separately with your husband to give your marriage another chance.
2. If you think it all but dead then engage an advocate and file a suit for divorce from where you are currently staying or is going to stay in near future.
3. You can bring criminal action against your husband and in laws as well by way of charges like section 498A, 406 IPC and 3 & 4 of D.P. Act.
4. You can claim maintenance and provision for your stay as well by way bring case under PWDV Act.
5. I must say that the litigation mentioned above likely to ruin your marriage for good. SO I would advise you to talk to your husband one last time to settle amicably.
All the best.
