Great question. First, if you honestly see yourself with a significant other that is willing and able to play those cards, you need to protect yourself before it happens. Be a few steps ahead of them. I could go into great detail of the shite I've dealt with over the years, but forgive me for not wanting to spew my bad decisions and dirty laundry on a public forum. I can, however, write a book and can at least give you some pointers. Like I asked earlier, is the other person willing and able to play those cards? Do they have absolutely nothing to lose and everything to gain? If you are dealing with someone with NPD, I gaurantee they've thought about all of this before you have. You cannot make this stuff up. By the time you get a handle on the way such a person thinks, you will be sitting there with your dick in your hand wondering HTF you ended up in such a shitty place only to discover that this person tactically set themselves up and covered every base they could. These people are very smart, but definitely not in a good way. Find out the laws in your state for recording, both audio and video and take advantage of it. If it is a two party consent state, you are screwed, but many states are a one party consent state. When it comes to domestic violence, as a man, you are 99.69% screwed even if she left marks on you and short of audio/video surveillence, the local PD is not going to bother bringing out a forensic pathologist to figure out who hit who first or if you were simply protecting yourself and left a mark on her in the process (or if she was drunk off her ass and fell on her own). She may not have a job. You have one that requires you to sign a Lautenberg statement to carry a weapon in the Armed Forces. You can't do that with a DV charge. If you are dealing with an escalating situation with a person like this, call the cops first and file a compaint whether she touched you or not. CYA. The more complaints the better, especially if she drinks a lot. Get it on paper so it can be used in court. If you have audio recorders/cameras in the house, more power to you. Pour all the alcohol in the house down the drain. If you have weapons, get them out of the house and give them to family or a good friend to store so the cops can't take them in the event SigO claims you threatened to kill her. If you are going through something as shitty as this, talk to your supervisor before they find out something from someone else. I know most of us dudes don't want to talk about shit like this with anyone, especially with a fellow coworker and in the line of business we're in, but it looks better for you in the event psychobitch decides to call your boss and threaten your career. Again, record as much as you can when you can to CYA. I would refrain from leaving the home without a court order forcing you to leave. Document, document, document.
