Dumb argument but maybe just communicate better?

My husband is a great guy and does a lot of good things for me. We have been traveling a lot and a trip popped up for his best friends bday. His gf wanted to have a surprise trip for the weekend and my husband told me that if they all ended up going if I would like to come. I said absolutely! Why wouldn’t I? Fast forward a week later we are in the car driving and he’s on his laptop and I see him booking a hotel. I asked him what he was booking it for and he said his friends trip anf that I’m not going. I gave a very surprised face and said “ok”. Then he starts telling me how he didn’t even invite me he said it was a maybe. He said his friends gf has a lot of friends in the city they’re going to do I wouldn’t be going. I was just confused about why he didn’t tell me earlier and that it would’ve just been fine if he said it was just the boys. Instead he turned it around and started arguing about the face I made. It’s so stupid but we were literally in the car for an hour and he said nothing to me as if I don’t exist. It’s not a big deal that he’s going but it wouldn’t kill him to just communicate with me instead of being rude. He then of course got all emotional and said stupid things he didn’t mean but it was ridiculous. I don’t understand why he acts like a little kid and took my face as an insult - I was just surprised since I felt like I was invited? He made it a point over and over again that I wasn’t going and I’m like ok I get it dude 👍
