Kids opened their presents without me

My husband is usually a great husband and father, but I am so effing pissed right now. I don’t think I’ve ever been this mad. I woke up this morning around 8:30 when I heard the kids running around. I knew they would be eager to open their Christmas presents so I got up immediately. I have a lot of trouble sleeping for various reasons so my husband lets me sleep in every morning and watches the kids until I wake up naturally or I have to get up to help get the kids ready for the day. He’s alone with them for half an hour to an hour. He knows what time to wake me up if I oversleep. So I come into the living room and there is wrapping paper everywhere. All the presents are already unwrapped and the kids (5 and 7) are playing with them. I immediately started crying and walked back into the bedroom where my sadness also turned into anger, and I started screaming like crazy. I am so, so mad. I spent so much time, thinking about what to get the kids, ordering it or driving around to find it in the stores, wrapping them and everything, and I feel like I was completely deprived of the joy of seeing their faces when they open their presents, which is one the best parts of Christmas. My husband said he videotaped it. I screamed at him why he either couldn’t make the kids wait, or he could’ve just come and woken me up. He just said “I never wake you up in the morning” I said “it’s fucking Christmas morning. You didn’t think I wanted to watch the kids unwrap the presents” and I called him an asshole.
He just said sorry, he didn’t say I overreacted. I’m really hurt right now and I don’t even know how to get over it. I don’t feel like doing anything Christmasy today. I’m so disappointed in everybody.
I guess this was more of a rant to get this off my chest, but you can certainly tell me if I was the asshole or not. Also, if you have any suggestions on how to mediate my hurt feelings, that would be really great. I hope you all have a merry Christmas. Edit: people seem to think that I cried and screamed and cursed in front of my children. I did not! I intentionally went into the bedroom to have a good cry. I wasn’t expecting to get so angry that I was screaming. My husband heard me and came into the room, so yes, I did scream at him and I did call him an asshole. I wish I had the same self control as so many in the comments that can control their strong emotions.
