Ego or something else?

Last night my husband(34/m) was shopping for winter vacations while I (36/f) was driving, then we got home and I finished a conversation I was having in the car and went to the kitchen to prepare dinner and lunch. I was concerned that it would take me a long time to prepare because another parent accidentally went home with Baby boy’s(12M) leftover lunch, which is usually his dinner in addition to some of what I make that day for dinner and lunch tomorrow. By then, I expected Husband to have walked our dog but he was still researching crosscrountry skiing trails. I probably distracted him more by making comments and asking questions. Then I reminded him that doggy needs to walk and he started getting ready to do that. He couldn’t find the harness at first so I dropped what I was doing to come help look for it. As soon as I came over our dog started acting strangely, he was running around desperately and I assumed it meant that our dog just couldn’t hold it in anymore. I told Husband what I saw and he had just found the harness. I asked for the harness but something happened during this time and he started yelling at me. I was really focused on helping the dog, so I grabbed a different harness. Husband yanked it out of my hand and kept yelling at me. This happened twice. By then I was really worried about our dog so I just opened the door and let him out without a harness, and I went with him. We were walking together to go find a place for him to pee and Husband went and intentionally woke up baby boy and came out side yelling. He ran over and grabbed doggy before he had a chance to go pee and continued yelling at me and also was hitting doggy in the face with the leash accidentally in his anger. Our dog was scared and wincing. I grabbed doggy back from hum and put him back down so he could pee. Husband said ‘I am going to go do something terrible,’ doggy went pee and together we walked back to the house. Husband was pulling a previously sleeping baby boy out of his carset and put him on the ground in the driveway crying. Be then I was back at the house so I immediately picked up Baby Boy and told Husband to get out. Husband walked doggy and when he got home he took my car and left for an hour or two. Husband didn’t help with Baby Boy but he didn’t stop me from caring for him either and he also walked Doggy the next morning before taking the bus to work. We haven’t spoken since. Husband would probably say that I ‘didn’t listen’ and might even call me ‘abusive.’ From my perspective Husband became irate and stopped caring about our dependents when he felt his ego was damaged by me. I am obviously going to put them before his ego, and if he can’t handle that then he needs to figure that out because screaming at us is not ok. Now if I mentioned this story he would probably say I am ‘just complaining,’ and that he doesn’t remember the details or why he got mad to begin with.
