Tough call.
There are two types of wrongful termination; violations of Title VII and violations of public policy.
If he's firing BECAUSE you're a woman, that's a wrongful termination under Title VII. If it's for another reason, it's not. Unless we can somehow turn his assault of you into a public policy violation. Whether we can or not is hard to say.
In general, a public policy violation is one in which you are fired BECAUSE you applied for or utilized a right or benefit under the law. That does not appear to be the case here, although you haven't said WHAT caused him to go into this tirade. I'm certainly not prepared to say that this is NOT a public policy violation, however, because i would think you have a right to expect not to be assaulted at work.
However, whether this is a wrongful termination or not, you certainly should look into all your legal options. Talk to a local attorney about what you can reasonably expect.
