Have you filed for divorce yet? At the minimum, once you file for divorce, you should request an immediate hearing to obtain an order of spousal support sufficient to allow you to pay rent.
You can also request continued health insurance through her policy or through payments by her sufficient to pay for your premiums and deductibles for a replacement policy. The sucess of your request for temporary support will be based on several factors, including how long you have been married and other income sources.
If available, you may have to take out student loans to supplement your income, stay in student housing, and obtain health insurance through the student health insurance policies at your school. I understand that some schools don't offer graduate students those options. However, undoubtedly, her attorney or the judge will ask you about those sources.
Finally, if either of you have already filed for divorce, check the standing court order. She may be in contempt of that order by moving and cancelling your insurance.
