We have had members apply for VAWA through Consular processing, not common, but I have seen it happen.
I do not think I have come across a case where the non USC has reported their spouse to USCIS, maybe I have forgotten, no reason of course why not. I see the main benefit is that this would make it very difficult for him to sponsor somebody else.
I agree with the other posters, your first focus should be getting your life back on track, filing for divorce, I think you have 2 years from the date of divorce to file VAWA. You can divorce in your home country.
