Am i in the wrong?

Me and my boyfriend have been together for 3 years, we have been doing long distance and i am finally moving to his city so the long years are coming to an end. we have been making plans for the weekend i move for about 3 weeks now. yesterday he calls me and asks if he can go to a whole different place with his friends that same weekend, and continued to say “i will see you everyday when i get back” i got angry and it felt really unfair because it feels like his friends always come first. he had even told me he knew a week prior about this trip but didn’t want to say anything about it because he knew how i would react yet continued to make plans with me. so am i in the wrong for saying no when i felt like my move should be a bit more important than the friends he sees everyday?
