Hello Dhammond, welcome.
I would most recommend first not taking it as personal- realizing it's driven by her ptsd (and likely anger and guilt and rage at herself, too). For your own feelings, peace of mind and quality of life, don't respond (get dragged into it), remain (emotionally and psychologically detached as much as possible- look upon her as ill and much of this is a symptom of her illness). Later, at a more 'sane' and less emotionally-charged time she may be willing to take responsibiliy for her behaviour, or acknowledge it; at that time or a calm time initiated by yourself (you can tell her you have to talk together and choose a time to speak together about it), you can express that you are worried she needs assistance, don't load her with guilt- show her by your words you understand and don't take it personally, but do not enable her, either (her denial will destroy your marriage if not her life and even possibly eventually kill her), do tell her it does hurt you and that you will cannot and will not accept that kind of response (make boundaries acceptable to yourself) and tell her what you will do (walk away next time if it occurs, etc).
I say that also with the caveat that everything is also within the 'timing' and go by your 'gut' instinct: there are moments in time for support that's critical, other times necessary to take a clear but harder stance.
I don't know if you have children but they cannot be allowed to remain privy to this, without being affected themselves. Hopefully there is a better way.
In the meantime read here like crazy to educate yourself, so that you really will understand and will have a 'roadmap' of sorts on what to do and not do, and also to get support for yourself. Do everything in your power to care for yourself, or you will not be able to help yourself or her. Get a therapist if you can, don't suffer alone. Express your fears.
I'm sure others will have other advice that may be even more useful, but I hope things work out for you and your family.
Best wishes to you.
