I'm fucking pissed! do I have the right to be?

Le
My boyfriend decided to go to motherfucking LASVEGAS with his friend for his friends brothers wedding. I from the begaining did not feel good with the idea and I expressed my concerns to him obviously. He kept telling me there's nothing to worry about and that he's still going! Okay so I decided I wanted to go to a concert which happens to be during the same time he's gone. He literally went ballistic and decided that I could not go and even though it seems bias he doesn't care I still can't go!? Like wtf 
1. I told you I did not want you going
2. He straight up didn't care about what I was telling him/ feelings.
3. He's a fucking hypocrite 
4. He still ended up going he's over there right now!
5. I'm left here stressing for no reason.
6. His bitch ass really thought I was going to be here waiting like I was a doormat 
7. I think Ima take my ass to the club and enjoy myself
