Unfortunately, unless you can prove that one or the other husband abused you, you need a U.S. Citizen husband sponsor. Since you entered the U.S., you have the following options:
1) Wait for the immigration reform that comes out. If it is approved the way that they are intending, then you may be able to get Residency if you entered the U.S. early
2) Apply for Asylum (you had to have done this within the 1st year be being in the U.S. unless there are changed country conditions), Withholding of Removal, Convention Against Torture, or Cancellation of Removal. The first three things are if you fear to return to your home country because you believe that you will be specifically targeted due to your race, religion, nationality, social group or political opinion and that you run a high risk of great bodily injury, torture, or death as a result. The last, Cancellation, you would have to prove that you have been at least 10 years in the U.S. AND you must also prove that if you are deported, a U.S. Citizen or Lawful Permanent Resident that depends upon you will suffer exceptional and extremely unusual hardship. This hardship must be something more than emotional separation hardship or financial hardship, so it is difficult to get.
3) If you marry a U.S. Citizen (for love, of course), you could file for Residency without having to leave the U.S.
4) Or if you have police reports and/or medical reports to prove abuse, you can apply for Residency on your own. Here is a link:
