AITA for refusing to let my kids go to their grandparents on Christmas without me?

For context Me and the husband have been together for 8 years married for 6, and have 2 kids together a 6yo and a 3yo. All this drama happened back in November. He works nights and we only have 1 car so when my oldest got sick and had to be taken to the ER late at night I had to call my family for a ride. My brother took us to the hospital a 15min ride from our house. We came to find out the next day that he was positive for Covid. I took my children and I to get tested and we were negative, that same day we were supposed to go hang out at my in-laws and after my husband talked to his parents we headed that way (his parents knew all about the covid test). When we got there his 2 sisters looked pissed. When I tried to make conversations the youngest talked to me with attitude. After like 5 mins her and my husband got to argue and she went after him like punching and kicking him (In front of my youngest) he never tried to hit her back nor hurt her. (I grew up with an abusive father that hit my mom so this was a huge trigger for me) Never before this I would imagine that she could do something like this, our relationship was amazing, i even considered her a sister. Anyway so we grabbed our stuff and left, I was livid and deleted both sisters from all social media platforms. A few days later (for Thanksgiving) my mother in law reached out to me to let me know how none of the "other ones" wanted to catch covid and how it was best if we stayed home. Of course I wasn't even planning on going in the first place but it still hurt big time. My family had been sick with colds even before all this happened and I was hit with it too so I was barely getting out. My father in law decided that since we couldn't attend nobody else could so he cooked and had everyone pick up the dinner to take home instead (as a way to no leave anybody feel left out).. my kids had 2 test done each both negative. I had 4 all negative as well, Im hurt specially because they're the kind of people who dont wanna get vaccinated, go out places like restaurants, bars, arcades without masks, have friends over all the time, and even live with people who travel out of state every weekend for work "to party". Now my husband and his sisters have patched things up, they even hung out a couple times, which its cool with me they are family and will always be. But I feel like they need to apologize to me. Now Christmas is coming and we are all supposed to go to my in laws, Im ok with my husband taking the kids for a bit but he wants to stay there the whole night and dont understand why Im upset. So Am I the wrong???

Also I found out that they had told their children to not play or get close to my kids that day, which made the kids ran out of the room when my oldest enter the room they were playing in, they tol him “ewww” when he tried to talk to them and ran way from him like he was some kind of pestered thing, he was very hurt and cried and kept asking why no body wanted him there.
