so october 21st of 2010 my current wife and i were married on the beach. we enjoyed ourselves for a good amount of time. ice came to our house and did a check after we went to our interview. and everything was good. two weeks later she moved out of our apartment left me hanging and moved in with her sister. i have no bills at their place in my name (thank god). however she and her sister have been threatening me that bad things will happen to me if i try to divorce her. she has still not gottan her green card. and her temporary drivers license and work permit are now expired. i have not gone to a lawyer yet with simple fear of her family trying to do something to me. can i sue her for using me, and threatening me. also whats the best way to go about the divorce with my safety in mind?
