Am I overreacting

sa

I have a 2 year old toddler boy who has an 830pm bedtime and a bedtime routine. My husband's father has a big Christmas party every year and my husband usually stays late and parties. I wanted to support him being with family so for the first time we decided that our son would go to bed late and we'd leave between 11-midnight. This was a big deal for me because I'm a stickler for his bedtime and if we have a party to go to my family watches him all night. I like him getting sleep and he sleeps so good!! Anyways, my husband gets lost in the moment with friends and family and loses track of time. At 1030pm my son was DONE. He was getting cranky, asked for his bedtime milk and only wanted me. I tried to rock him and put him down but he wasn't having it. I told my husband what was going on and we had to leave. My husband didn't want to go and started singing with his sisters on the microphone in front of everyone. Meanwhile my toddler is getting crankier. I couldn't drive home because I had one contact in (long story). I knew my husband would sing until morning so I went to him while he was singing and in his ear told him we had to go. He said loudly "are you trying to take me from my family?" I was embarrassed and he made me look like the bad person trying to rob him of family time. Of course no one knew that we had discussed a plan, how this was already hard for me, and I already tried to pull him away. It took me 30 minutes to get him out of there and he was so rude to me. I cried in front of his father in law who said he was on my side but I'm sure I looked crazy. I'm SO upset because I tried to do something nice and he didn't help me when it was time to go. Am I overreacting for being so upset?
