Am I wrong?

So the Daytona race is coming up this weekend and I have wanted to go the last 3 years and my spouse and I haven't been able to...well this year I said again I'd like to go and of course we would have to find a babysitter. So my spouse tells me tonight he's going to a friend's this weekend (whom we were supposed to go to the race with but none of us ever got tickets) and his wife is going out of town so it will just be the my husband and his friend and I have told him if he goes to the race I will literally leave. Am I wrong for this? I feel like the level of disrespect if he did go with his friend knowing I wanted to go but couldn't due to us not being able to find a babysitter is just beyond me. We've been together 10 years and im ok with him going to his friends house and relaxing as he told me they were going to do but I can't help but feel like they are going to go to this race. If they do go to the race am I wrong for feeling like it's disrespectful as fuck to me and wanting to leave? And yes my kid is his kid so if we didn't find a babysitter I feel like neither of us should be able to go and why go make memories with your friend when you knew your wife wanted to go. ??? Only reason I ask about the wanting to leave if he does this is because he has cheated recently in the last 3 months and we are supposed to be working on trust so if he lies to me about something like this then I feel like I have all rights to leave when he knows how I feel about the whole situation and why I feel the way I do.
