ADHD Spouse, poor verbal impulse control and lashing out

Often when my ADHD husband gets stressed out, he will lash out and give a laundry list of reasons why he's stressed out, and each and every thing he lists seems to have a barbed comment about how I've failed/let him down in some way. I've told him how this behavior makes me feel, but he insists that if I can't repeat exactly the things he said that were offensive he "can't change the behavior." This really feels like a cop-out and refusing to take responsibility for the things he says. I'm struggling because when it's a long list he's rattling off (which feels like kitchen sinking) I don't know how I'm supposed to remember every single word he says like a tape recorder, I just know how it makes me feel. He refuses to see any good I do, whatsoever, and is always the victim in the scenario, and I am always the villain. 

For instance, this evening I made dinner, packed up our kiddo's daycare snacks for tomorrow, made up the bed (our 22 month old is potty training and had an accident on our bed), and put away the food from dinner. There were a few dishes left (a pot, some toddler dishes, cutting board, and a couple spatulas) and a little lunch left to pack. Our dogs desperately needed a walk and were begging to go out, so I told him I was going to take them around the block (about a 20 min walk normally) and be right back to help with the rest of the bed time routine. He was giving our son a bath and he said "of course, no problem, and if you need to leave some dishes or lunch packed for tomorrow it's fine I can do it." I leave for 20 mins. When I came back he was stressed out and packing lunch for kiddo's daycare. I asked what still needed to be done for bedtime and what I could help with and he went into this tailspin about how "everything needs to be done," and I left all this stuff for him to do and he had to shoulder it all alone. (This was after he told me to go walk the dogs and I told him what was remaining) I was just going to let it slide but I think he could tell I was a little annoyed by this sudden 180, and was breathing down my neck to repeat the exact words he said that had offended me. He spiraled out and we ended up not solving the issue. He went for a long walk for hours and is sleeping in another room tonight.

It just feels so crazy to even be in a place like this, and this kind of thing happens more than I'd like to admit. I don't know how else to make him understand the things he says are hurtful and if he could even say them in a neutral way or act like we're a team to any degree things would be peachy.

Anyone else experience something like this?
