help with my relationship

i’m in a relationship of 2 years with someone i’ll call Ben (that’s not his real name btw), he’s my first boyfriend or my first everything if you can call it. he feels upset because my parents won’t let me go to trips with his family. My country is full of beaches and for NYE they always stay at a resort on a beach 2 hours away from my home. But my parents are strict with that matter, they won’t let me go because they’re scared something bad might happen but honestly i feel it’s because when my parents were dating my grandparents made my dads life impossible. He had many reasons to walk away from my mom because of it but he didn’t, and one of the rules they set for them was that, they wouldn’t go on trips beyond the city together. So i know it’s bad, but i’m used to that and my boyfriend isn’t which i get, but i tell him that with more patience overtime they’ll let me go someday, but he’s over it. He said to me that he will be patient but his patience won’t take long if it happens again. He’s not mad at me but he’s mad at my parents for not letting me go with them, feeling that my parents dont trust him or his family enough to let me go. Even though i’m sad i’m not there with them, i treat him like i always do with love and care but he doesn’t because he’s uncomfortable, so he’s been petty the entire weekend. And i’m sure he will be petty the entire week if he wants to. I really don’t want my relationship to end over something that could be fixed. He’s even more mad because i will be away from home for two months living in a commiunuty working in a primary care center because of school. And he finds it ironic how they’re okay letting me stay over there for two months but not even a weekend with his family, and i get that. But i feel powerless over the situation because i know that my parents will say that if my boyfriend can’t put up with that then he wasn’t the one for me. I just don’t know how to talk to them. They say that i have to live by they’re rules while i’m under they’re roof. And i even can’t move out because i’m just a student, and i dont want to damage my relationship with them either.
