husband infuriates me

So I found out through a friend of ours my husband planned a boys trip to see a concert in Vegas. The tickets are already purchased. He justifies this because he mentioned a month ago he 'would like to go' and thinks I'm overreacting. I'm not concerned with the actual trip or the group he's going with, but the communication or lack there of. I also want to add that for months I've been trying to plan a family trip but can't get a commitment from him. I really didn't want my son growing up with a broken family but not sure how much more I can put up with. 😡
