extreme anger /behavior from non-ADHD spouse

Hello everyone, I am relatively new to this forum and definitely relatively newly accepting of the fact I have ADHD. To make a long story short I have been married for 15 years. Only in the last year or so have I accepted the ADHD tag and tried to do something about it. And for the first few months my efforts were pretty half hearted. I am now taking drugs...So my wife has been dealing with this for a while and had built up a lot of resentment and anger towards me. We have our first child now and he is an infant still. This baby has accentuated all our problems and definitely exposed my issues greatly especially with lack of sleep... I could keep going but I have noticed on this forum it seems that the angry person is often the ADHD person, not the other way around as it is with my situation. Problem is she has so much frustration that it has boiled over into abuse in my eyes. She has slapped me, pinched me and yelled at me and called me all kinds of names and says she hates me, wishes we never met etc. She used to apologize for this but now she feels completely justified. I used to think she didn't mean these things but now it is always bad it seems the past week or so. I have considered she might have post partum depression but it doesn't really matter because she won't look at her self anymore. Only blames me for all problems. And it's hard for me to argue with her because I can see how frustrating it is. Anyway. Anyone else have this issue and if so what are your suggestions? Thank you
