Too early in the day for feminism on GD, and if there's more to the story feel free to resurrect the Relationships thread. Don't really have the time to do you an essay on feminism and various bromisms for you, but let me offer you some further options.
5a. Listen to your partner, and let her state her case. You'll then know what the points of difference clearly are. Both agree to refer to wonderful places of expertise like the ONS in advance, for example, to resolve matters of dispute that claim either a particular point of fact or conclusion from anecdotal evidence, which is offered as an independently verifiable empirical law when it clearly isn't upon some reflection (without an independent arbiter like this, it's just a row). Be bold: dig up your material and hers to read and compare side-by-side, check the sources and listen to experts with some bias or none (a meta study of sorts). Talk about your past and how it shaped your views openly. If your previous experiences haven't entirely wiped out your critical faculties, you should then be able to admit where you were right, wrong or undecided. Once matters of fact are eliminated, whatever remains is opinion you can reach a happy disagreement on. Social sciences are far from perfect: be cognisant that what applies in the US may not apply in the UK or even a region of it, as a for instance; be mindful of generalisations.
5b. Convert all that tension into sexual energy -- everyone's a winner.
6. Stay away from Lizard Queen conspiracies of the evil, conspiring matriarchy that's been the power behind the throne all these centuries. It's popular in certain self-help works, implicitly or explicitly, for a reason -- it works on and sells books to the target audience.
7. A few weeks pass and you still treat each other as chess rivals? Then it's perhaps time to amicably part, as one or both of you went with biology over engaging brain, and, hey, that's just how it is at times. With good sense, you both would've learnt something from the experience.
Or you can keep running up that hill with your red pill

In summary: bad people exist; women can be just as irrational and as abusive as men in relationships, sure; nonetheless, a rotten life still does not justify a leap of faith and a priori dismissal of a point of view that's encapsulated in the words 'she dares to disagree with me -- time to go my own way!' The latter on the internet, in my biased and limited experience, is far too often wounded pride and a touch of cowardice talking.
