Book Confusion: Projection?

I am nearly done reading the book and finding it very insightful. My wife was recently diagnosed with ADHD and started meds. As the non-ADHD spouse, I am reading the book trying to place myself in those shoes. 

While I clearly see her symptoms (disorganized, excessive spending, distractible, etc), she is also very much the book version of the non-ADHD spouse. She nags, belittles, rages at me, pushes all real responsibilities on me then tells me I contribute little or nothing, and is constantly asking me to do more. I never ask her to do anything and go out of my way to avoid triggering her anger. 

I am the described easy going, fun loving, spontaneous, hard working, loving parent. I can certainly get distracted or have my attention pulled in too many directions, but I believe to a reasonable degree. I have not been evaluated for ADHD, it has never been recommended (except by her) and the screening questionnaires come up negative. 

I am the sole bread winner, cover all bills and finances, am expected to cook every meal (separate meal for her to eat on her own typically), take kids to every birthday party / practice / sporting event, all kids are in school or day care and we have a cleaner come. I don't drink, play video games, go to the gym, or go out with the guys (no time). I 'walk on eggshells' constantly. 

From what I read in the book, it seems like she is managing me like I'm the ADHD spouse and not the other way around. Could she be projecting her symptoms and frustrations on me to deal with her ADHD? Is this a known pattern?
