As posters have said, either divorce and file with a waiver or fix your marriage and file together. There is no in between. Are you beaten and battered or just nagged about the car ?
If you divorce you don't have to wait either. Based on what you wrote you should not file an abuse waiver I-751, because it would most likely get denied.
Either patch things up and file jointly when the time comes or divorce and file a divorce waiver I-751.
1. You have what is called a conditional green card, not temporary.
2. You either want your marriage to work out (why would you with an abusive spouse) OR you want to file using VAWA, BUT NOT BOTH. And you certainly don't use VAWA while living in the house with the abusive spouse.
3. Like mimolicious said, if you file for divorce and apply to remove conditions with a divorce waiver and provide evidence that the marriage was entered into in good faith, then you will have the upper hand and no letter that she can write will cause USCIS to deny your application. Please do not listen to or believe any US spouse who claims they will "take your green card away" as a means to control you or because the marriage is not working out. US citizens have no such power.
4. This is an immigration website so if you want to stay married to and live with your abusive spouse, you really have no business asking questions here because you are not really seeking any immigration advice. You cannot file for a waiver as a battered spouse and then go home and have dinner and snuggle in front of the TV with that spouse.
If you divorce and have proof that the marriage was entered to in good faith you can get a divorce waiver if you have not yet removed conditions on your greencard. Not sure what you mean by a "waiver for being battered" there is no such thing. Where in the immigration process are you? You have given no details
