Here is another link to read over....Your marriage has to be terminated at the time you file for the waiver for good faith. You cannot do that while you just seperated.

If the marriage is terminated, yes you can use the waiver and be granted the removal. I am sure the ICE will scrutinize the claim closely, and any documention you may have...letters, police reports...would help..
