It is unlikely your wife can take your green card back. Only an immigration judge [IJ] may do so and then, only upon DHS' showing that you violated the law or that you got your green card by fraud. Based on your account, it seems that you have a good faith marriage and at least with respect to that, you did not obtain your green card by fraud. That said, you need to file a Form I-751 within 2 years of the anniversary of getting your green card. Where there is marital harmony, the I-751 is filed jointly by the couple. But where as here, your wife is unwilling, you can file the 751 without her. If you file alone, you must provide concrete evidence that (a) your marriage was genuine and (b) explain reasons why cannot file together that you are not at fault, either due to divorce, or as I suspect your wife's abusive nature . There are two important things you must note. 1. Start getting documents and statements and other information that shows your good faith marriage and reasons for your break up, if that is what eventually happens. Next, although, it appears you are the victim of acts of your wife's domestic violence, you must at all costs avoid any altercation situation that may result in you, the victim, being convicted of domestic violence. Such conviction without further ado may result in your permanent deportation from the US. In the end, I believe your best interest is served best if you hire an attorney right away.
