Am I wrong?

Okay so my bf and I have been together for over a hear and westarted  college in august as a long distance relationship. Everything is great we saw each other for a week in october and we will see each other saturday.
He works at his parents restaurant on the weekends but is taking off early to take me out to dinner.
My family is going to mass saturday night and i invited him to come with us. (He is catholic also so thats not the issue)
He told me that he will tell me on saturday if he can or not.
Im just annoyed because he finishes work 30 minutes before church starts and live 10 minutes from me. wI feel like he is making work more of a priority then being with me and spending time with my family.
I have always been close with my family and so is he so I dont get why he would do that.
